* module/ice-9/psyntax.scm: Use the vector representation of source
properties internally. We have to convert to alists when going to
Tree-IL, but this will be in harmony with syntax objects once the reader
switches to vectors too.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm: Add a special case for (). There are
already special cases for pairs, vectors, etc; the issue is that with
read-syntax, the () might be come into psyntax as an annotated syntax
object, which here we would want to strip, to preserve the invariant to
psyntax users that all lists are unwrapped.
* module/ice-9/psyntax.scm: With the new behavior of datum->syntax which
allows #f for the lexical context, we have the question of what module
to attach to these newly created syntax objects. In that case we'll
mark down #f as the module, indicating that we know nothing. We have to
extend a number of other cases to default to the expander's idea of the
current module, if a syntax object has no module scope.
Also, change datum->syntax to attach the empty wrap, not the top wrap.
Attaching the top wrap leads to multiply applying the top mark, as you
recurse into subexpressions.
* module/ice-9/psyntax.scm (strip): It used to be that terms in the
source program could have a "top" mark, and when stripping marks we'd
stop recursing when we see an expression with the top mark. This had
the good effect that source programs could contain quoted syntax
objects, or quoted objects with shared structure -- in theory anyway.
In practice the compiler didn't support objects with shared structure.
Anyway when we switch to "read-syntax", quoted expressions can contain
syntax objects introduced by the reader, which naturally we would want
to strip away in a (quote FOO) form. Therefore we remove the
top-marked? optimization.
* module/ice-9/psyntax.scm (quote-syntax): New core form. Usually the
expander will unwrap all syntax objects from the input term. However
sometimes you want to preserve a syntax object, as a datum. That's
when you want quote-syntax.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/local-eval.scm (identifier-syntax-from-box): Use
quote-syntax instead of our datum->syntax trick, which relied on
psyntax's special treatment of the top mark.
* doc/ref/api-macros.texi (Syntax Case): Update documentation for
datum->syntax.
* module/ice-9/psyntax.scm (datum->syntax): Use #:source keyword for
source location info instead of an optional, and allow an alist.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/read.scm (%read, read): Refactor to allow read and
read-syntax to share an implementation.
(read-syntax): New function.
* doc/ref/api-macros.texi (Syntax Case): Document that template-id can
be false, and document srcloc.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (syntax?): Allow the lexical context to be
null. Allow srcloc to be a source properties alist. Inspired by
Racket.
* module/ice-9/psyntax.scm (datum->syntax): Add an additional optional
argument, to allow callers to provide source annotation information.
* module/ice-9/psyntax-pp.scm: Regenerate.
* libguile/syntax.c (scm_make_syntax): Add optional "source" argument.
Note that this function is internal.
(scm_syntax_source): New function, replacing definition in boot-9.scm.
* libguile/syntax.h: Add new declarations.
* module/ice-9/psyntax-pp.scm:
* module/ice-9/psyntax.scm (source-annotation): For syntax objects, the
source annotation comes direct from the syntax object.
* module/system/vm/assembler.scm (link-data, intern-constant): Write
5-word syntax objects.
* module/ice-9/read.scm (read): Use R5RS read-char, peek-char,
write-char rather than (ice-9 textual-ports) wrappers, because the
latter are expressed in terms of the former.
* module/Makefile.am (SOURCES): Add ice-9/read.
* module/ice-9/read.scm: New file. The idea is to move the compiler to
use this "read", after proving that it does the same as C. Then we
can switch to read-syntax that returns syntax objects with source
locations, allowing us to annotate any datum.
* module/ice-9/binary-ports.scm (call-with-input-bytevector):
(call-with-output-bytevector): New functions.
* module/ice-9/iconv.scm: Remove superfluous copies of
call-with-output-string* and call-with-output-bytevector*, now that
the former closes the port and the latter exists.
(call-with-encoded-output-string): Adapt.
* module/web/uri.scm: Use (ice-9 iconv) instead of local
bytevector/string conversion procedures.
* module/ice-9/ports.scm (call-with-port): New procedure, from r7rs.
(call-with-input-file, call-with-output-file): Refactor to use
call-with-port.
(call-with-output-string): Close the string after normal exit.
* module/scheme/base.scm (scheme): Re-export call-with-port from base.
* module/ice-9/boot-9.scm (%auto-compilation-options): Add

they are subsumed by use-before-def. There are some deprecated
bindings though.

multiple
* module/system/base/message.scm (%warning-types): Add handlers for the
new warning types.
* test-suite/tests/tree-il.test: Add tests.
* doc/ref/api-evaluation.texi (Compilation): Update.
* module/ice-9/popen.scm (open-process)[unbuffered, fdes-pair]: New

* module/ice-9/match.upstream.scm (match-next): Use throw, so that CPS
can see that there's no fallthrough.
* module/ice-9/match.scm: Add a note about what to do in 3.1 to remove
the old "error" definition.
This is an opportunity to make a new interface that can be more
efficient in 3.0 (because no generic array support), easier to read (no
need for 'not'), and more consistent with other bitvector interfaces.
