* libguile/expand.c (expand_letrec_helper): Factor out common code.
(expand_letrec): Use expand_letrec_helper.
(expand_letrec_star): New primitive syntax: letrec*.
* libguile/memoize.c (memoize): Add memoizer support for in-order letrec
(letrec*).
* module/ice-9/psyntax.scm (build-letrec): Another arg, `in-order?'.
(chi-body): Adapt to build-letrec change. We don't yet use letrec* for
internal definitions.
(letrec): Adapt to build-letrec change.
(letrec*): New expander.
* module/ice-9/psyntax-pp.scm: Regenerated.
* libguile/expand.h (SCM_EXPANDED_LETREC_IN_ORDER_P)
(SCM_MAKE_EXPANDED_LETREC): Add a new field to letrec, in-order?. Will
be used to support letrec*.
* libguile/expand.c (LETREC, expand_named_let, expand_letrec): Adapt
code.
* module/language/elisp/compile-tree-il.scm (compile-pair):
* module/ice-9/psyntax.scm (build-named-let, build-letrec): Pass #f for
in-order? to `make-letrec'.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/language/tree-il.scm: Add letrec-in-order? accessor.
(parse-tree-il, unparse-tree-il): Parse and unparse an in-order?
letrec as `letrec*'.
(tree-il->scheme): Serialize letrec*.
* libguile/expand.c (expand_lambda_star_case): Harmonize with tree-il,
expanding keywords to (aok? (kw name gensym) ...), not
(aok? (kw . index) ...).
* libguile/memoize.c (memoize): Process the (kw name gensym) format into
(kw . index).
* module/ice-9/psyntax.scm (build-lambda-case): Remove a
compile-versus-eval special case.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/eval.scm (primitive-eval):
* libguile/eval.c (scm_c_primitive_eval): Don't expect a memoized
expression -- expect either raw source or an *expanded* expression. We
handle memoization ourselves.
* libguile/expand.c (scm_macroexpand): Settle down into its proper name,
"macroexpand", even as we comment that it is but a fleeting boot
expander.
(scm_macroexpanded_p): New predicate for expanded code.
* libguile/expand.h: Add scm_macroexpanded_p.
* libguile/memoize.c (scm_memoize_expression): Require that the
expression be expanded.
(scm_init_memoize): Don't alias memoize-expression to macroexpand.
* module/ice-9/psyntax-pp.scm:
* module/ice-9/psyntax.scm: Always produce macroexpanded expressions,
and hand them to primitive-eval. No more calls to memoize-expression
here.
* test-suite/tests/optargs.test: Remove some tests, as unfortunately we
have no way to invoke the boot expander after boot.
* libguile/Makefile.am:
* libguile/init.c:
* libguile/expand.c:
* libguile/expand.h: Add new expander. The idea is that macroexpansion
is one thing, and whether to compile or interpret the result of that
is another thing.
* libguile/memoize.c: Adapt to expand as necessary, and then memoize
expanded source without worrying about syntax errors.
* module/ice-9/eval.scm (make-general-closure): Allow alt clauses to not
possess the full make-general-closure arity.
