Hi,
Adding my two cents to the "wish list"...

I believe the major interpreter performance improvements are to be
gained by algorithmic optimizations (e.g., closure invocation, variable
lookup), rather than micro-optimizations such as JIT. That said, JIT is
a fascinating domain. :-)

I'm (still) interested in comparing the space/time tradeoff in Guile and
the `libgc'-based Guile. We'll see.
Besides, I think using libgc would yield a number of practical
improvements for the end user: `scm_set_smob_mark ()' would become
useless in most cases and so would `scm_dynwind_free ()',
`scm_set_smob_free ()' could be avoided almost entirely in guile-core,
memory leaks would become less likely in the presence of non-local
exists, marking a tree-like structure would just work (see
http://thread.gmane.org/gmane.lisp.guile.bugs/3558), etc.

As Neil suggested, I'd say "no" for the time being.

Right. I've been meaning to update the projects page for a while
actually...

I'm not too fond of CIL/Java bytecode, but choosing the bytecode format
should not be the most difficult thing. ;-)
OK, so my goals for 1.9 would be:
* Evaluate `libgc'-based Guile (see above).
* Rewrite the interpreter in Scheme (or a subset thereof), with a
tiny Scheme-to-C compiler. That could be done in such a way that we
could re-use, e.g., the memoization and unmemoization code that
already exists in the first step.
* Provide a documented C doc snarfing tool, written in Scheme, with a
public Scheme doc snarfing API. I started looking at it based on
the modules I wrote for doc-snarfing in Guile-{Reader,Avahi,GnuTLS}.
* Provide some Unicode support. The hardest part, I think, is that
we'd probably need to rewrite/extend the C port API.
Comments?
Thanks,
Ludovic.
