* module/language/scheme/translate.scm (*the-compile-toplevel-symbol*):
Reset to compile-toplevel, which requires a patch to guile.
* module/system/base/compile.scm (compile-file): Some foo so that we load
up the scheme language before call-with-output-file. Fixes compilation
of (language scheme) modules.
* module/system/base/language.scm (define-language): Don't unquote in
make-language; refer to it by name instead, and export it.
* module/system/repl/Makefile.am (vm_DATA): Don't compile describe.scm,
because we really can't deal with goops yet.
* module/system/repl/repl.scm (compile-toplevel): If we're compiling, put
in a stub definition of start-stack, which is closely tied to the
interpreter.
* src/vm_loader.c (load-program): Fix a very tricky corruption bug!
* module/system/repl/repl.scm (default-pre-unwind-handler)
(default-catch-handler): New procedures, to do some error handling in
the repl.
(start-repl): Catch errors in the repl loop.
* module/system/base/compile.scm (<cenv>): No more cenv, it was a useless
data structure.
* module/system/repl/command.scm (*command-table*): Remove `use', it's
the same as `import'. Otherwise in this file, adapt to the repl having
direct pointers to the vm and the language, and to the module being in
the current-module fluid.
* module/system/repl/repl.scm (prompting-meta-read):
* module/system/repl/common.scm (<repl>): The repl now has a direct
pointer to the vm and language. Adapt accordingly.
* module/system/repl/common.scm (repl-prompt): Return a string instead of
outputting to the port, for better readline integration.
* module/system/repl/repl.scm (meta-reader, prompting-meta-read)
(start-repl): Integrate with (ice-9 readline) via the current-reader
fluid and the repl-reader function, both from boot-9.scm.
* module/system/repl/command.scm (system): Declare exports in the module
declaration.
* module/system/repl/repl.scm (start-repl): If the evaluation returns
multiple values, print them separately.
