hash-table accessors.

* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (expand-body): As required by R6RS, evaluate
the right-hand-sides of internal 'define-syntax' forms and add their
transformers to the compile-time environment immediately, so that the
newly-defined keywords may be used in definition context within the
same lexical contour. Fixes#13509.

expression, not to the expression's compile-time environment.

* module/system/repl/repl.scm: Update to use current-language parameter
and parameterize.
* module/ice-9/boot-9.scm (make-parameter): Add a docstring.
(fluid->parameter): New interface. Use it when turning port fluids
into parameters.
* doc/ref/api-scheduling.texi (Parameters): Deffn instead of defun for
make-parameter documentation. Add docs for fluid->parameter.
* module/ice-9/psyntax.scm (include): Like `load', interpret relative
paths as being relative to the file that does the `include'.

* libguile/load.c (scm_primitive_load_path): If the second argument is a
procedure, call it like a thunk.

* module/language/assembly/disassemble.scm (code-annotation):
* module/language/assembly/decompile-bytecode.scm (decode-load-program):
* module/language/assembly/compile-bytecode.scm (compile-bytecode): Add
case for bind-optionals/shuffle-or-br.

is an alternate, use bind-optionals/shuffle-or-br instead of
bind-optionals/shuffle.
* test-suite/tests/optargs.test ("case-lambda*"): Add tests.
* module/ice-9/iconv.scm (call-with-encoded-output-string):
(string->bytevector, bytevector->string): Take an optional instead of

Fixes <http://bugs.gnu.org/12173>.
Reported by Ian Price <ianprice90@googlemail.com>.

it as the second argument of `SCM_M_LAMBDA'. Update caller.
(memoize)[SCM_M_LAMBDA]: Extract docstring from EXP; when `memoize'
returns, add the docstring to the lambda's arguments.
(unmemoize)[SCM_M_LAMBDA]: Adjust to new argument layout of
`SCM_M_LAMBDA'.
* libguile/eval.c (BOOT_CLOSURE_NUM_REQUIRED_ARGS,
BOOT_CLOSURE_HAS_REST_ARGS, BOOT_CLOSURE_IS_REST,
BOOT_CLOSURE_PARSE_FULL): Adjust to new argument layout of
`SCM_M_LAMBDA'.

(scm_sym_documentation): ... this. Make it global.
* libguile/procs.h (scm_sym_documentation): New declaration.

New `scmstat' parameter; use it.
[sans-extension]: New procedure.
[load-absolute]: Call (stat ABS-PATH) from here. Search a `.go' file
from %LOAD-COMPILED-PATH before searching %COMPILE-FALLBACK-PATH.
This allows it to actually use all CPU cores, instead of having the main
thread stuck on a `wait-condition-variable'.
* module/ice-9/threads.scm (par-mapper): Add a `cons' argument; update
callers accordingly. Rewrite using nested futures.
* module/ice-9/futures.scm (%futures-waiting, %within-future?,
%future-prompt): New variables.
(let/ec): New macro.
(process-future!): Run FUTURE's thunk in a prompt; capture FUTURE's
continuation when it aborts, and add it to %FUTURES-WAITING. Set
%WITHIN-FUTURE? in the dynamic extent of the call FUTURE's thunk.
(process-futures): Move loop body to...
(process-one-future): ... here. New procedure.
(notify-completion): New procedure.
(touch)[work, loop]: New procedures.
When %WITHIN-FUTURE? and FUTURE is started, abort; if not
%WITHIN-FUTURE, call `work' while waiting.
When FUTURE is queued, call `work' too.
* test-suite/tests/future.test ("nested futures"): New tests.
* module/ice-9/futures.scm (<future>)[completion]: New field.
[done?]: Rename to...
[state]: ... this. Change `set-future-done?!' to
`set-future-state!', and `future-done?' to `future-state'.
(make-future): Initialize the `completion' field to 'queued.
(with-mutex): New macro.
(process-future!): Remove `set-future-done?!' call.
(process-futures): Check `future-state'. Unlock FUTURE's mutex before
processing it. Broadcast FUTURE's `completion' cond. var. when done.
(touch): Likewise.
* module/ice-9/futures.scm (%create-workers!): Use 'with-mutex' in case
an exception is thrown. Within the critical section, check to make
sure the worker pool hasn't already been created by another thread.
* module/ice-9/getopt-long.scm (%make-option-spec): Fix the formal
argument list to match the actual fields present.
(make-option-spec): Update to match the fixed %make-option-spec.
Reported by David Pirotte.
* module/ice-9/futures.scm (process-futures): Wait on %FUTURES-AVAILABLE
only when %FUTURES is empty.
The problem was obvious when running (begin (use-modules (ice-9
threads)) (par-map 1+ (iota 400000))) : eventually, only the main
thread would do the work, while the others would remain idle, waiting
on %FUTURES-AVAILABLE.
* libguile/private-options.h: Add SCM_CURLY_INFIX_P macro, and increment
SCM_N_READ_OPTIONS.
* libguile/read.c (sym_nfx, sym_bracket_list, sym_bracket_apply): New
variables.
(scm_read_opts): Add curly-infix reader option. Reformat to comply
with GNU coding standards.

curly_infix_p is set.
(set_port_square_brackets_p, set_port_curly_infix_p): New functions.
(read_inner_expression): New function which contains the code that was
previously in 'scm_read_expression'. Handle curly braces when
curly_infix_p is set. If curly_infix_p is set and square_brackets_p
is unset, follow the Kawa convention: [...] => ($bracket-list$ ...)
(scm_read_expression): New function body to handle neoteric
expressions where appropriate.
(scm_read_shebang): Handle the new reader directives: '#!curly-infix'
and the non-standard '#!curly-infix-and-bracket-lists'.
(scm_read_sexp): Handle curly infix lists.
* module/ice-9/boot-9.scm (%cond-expand-features): Add srfi-105 feature
identifier.
* doc/ref/srfi-modules.texi (SRFI-105): Add stub doc for SRFI-105.
* doc/ref/api-evaluation.texi (Scheme Read): Add documentation for the
'curly-infix' read option, and the '#!curly-infix' and
'#!curly-infix-and-bracket-lists' reader directives.
* doc/ref/api-options.texi (Runtime Options): Add 'curly-infix' to the
list of read options.
* test-suite/Makefile.am: Add tests/srfi-105.test.

* module/ice-9/boot-9.scm (define-option-interface): When printing
options help, e.g. for (read-options 'help), expand the width of the
first column by another tab stop, to accommodate option names of up to
23 characters.
* module/ice-9/regex.scm (fold-matches): Set regexp/notbol if the
starting position is nonzero.
* test-suite/tests/regexp.test (fold-matches): Check that when
matching /^foo/ against "foofoofoofoo", only one match results.
