core Guile distribution, because we don't have copyright
assignments for this code. We can certainly distribute them as a
separate package, but Guile should be FSF code.
* syncase.scm, psyntax.pp, psyntax.ss: Removed.
* Makefile.am (ice9_sources): Removed syncase.scm, psyntax.pp, and
psyntax.ss.
* Makefile.in: Regenerated.
* Makefile.am (ice9_sources): Add getopt-gnu-style.scm.
* Makefile.in: Regenerated.
* slib.scm: Added hack which transfers syntactic information from
the builtin variable `define' to the slib version if module (ice-9
syncase) has been loaded. This is necessary to get correct
expansion inside the slib module.
* psyntax.ss (build-let, build-named-let): New output
constructors.
(build-lexical-var): Seed gensym with symbolic name.
(self-evaluating?): Add keywords among self-evaluating types.
(let): New core form.
(if): Removed from core language.
(or, and, let, cond): Removed syntactic definitions.
(sc-expand3): New procedure: Expander which takes optional mode
and eval-syntactic-expanders-when arguments.
* syncase.scm (psyncomp): New procedure: Recompiles psyntax.pp.
Should be used inside the (ice-9 syncase) module with (use-syntax
syncase) and with the current directory containing the psyntax.ss
source.
Added hack to transfer syntactic information from the builtin
variable `define' to the slib version if module (ice-9 slib) has
been loaded.
* syncase.scm (putprop, getprop): Modified to use the object
properties of the variable object corresponding to the symbol;
This way we can ride on the mechanisms of the module system.
Changed `builtin-variable' calls to `define-public' calls.
Setup the hooks sc-expand and sc-interface.
* boot-9.scm (sc-interface, sc-expand): New builtin variables.
(set-current-module): Switch to and from sc-expand as
scm:eval-transformer when going into and out of modules using
syncase macros.
(module-use!): Set scm:eval-transformer to sc-expand when adding
the syncase interface.
