Subject: Compiler messages
"Currently, it feels like monthly is going to be about right" - Me, in SG2
A statistician really should know better than to make wild predictions!
I've had a few email submissions and some of them really do need to be
sent out this week to be useful. So, here's a small but nicely-rounded
round-up circular for you all.
Please, still email me about the format changes and sending frequency,
or send notes to include (max 19 lines of 75 chars, please).
In this edition:
- new libraries, new versions, htmlprag poll, plug
- Chicken 1.66
- Scheme UK Meeting: 2 September 2004
- Scheme Workshop
- mod_scheme final tests
- SISC 1.9.0-alpha

Httper 0.3 now uses "uri.scm" instead of UriFrame.

Please email Neil if you have any opinion at all about whether or
not the main HtmlPrag library should depend on Pregexp.
Also, Neil is looking for a job that would permit him to use Scheme.
See his site for more details about his interests.

The CHICKEN Scheme-to-C compiler has an improved new version, with
bugfixes, -ffi-custom, -split and -split-level options, new foreign types,
improved FFI parser, tilde expansion in filenames, improved library,
eval, posix, extras, lolevel and syntax-case units, better Cygwin setup
support, define support of curried syntax, csi changes and much much more.

Subject: Scheme UK: London, 2 September 2004

The next meeting of the Scheme UK user's group will be held on Thursday, 2
September 2004 from 7pm till we leave for the pub. The meeting will take
place at the offices of LShift (see http://www.lshift.net/contact.html
for directions). This meeting will be held in conjuction with UK Lispers.
The (soon to be announced) Scheme Cookbook is an effort to produce
practical documentation for Scheme, presently online but with an eye to
future publication. Noel Welsh will discuss the implementation of the
Cookbook, the goals and some of the thorny issues such as the currently
contentious licence.

A call for participation in the ACM SIGPLAN 2004 Scheme Workshop at
Snowbird, Utah, USA on 22 September, 2004 has been issued.
This is part of the 2004 International Conference on Functional
Programming (ICFP).

Subject: mod_scheme final tests
X-URL: http://blufox.batcave.net/mod_scheme.html
A Scheme module for the Apache protocol server. Many updates have been
checked into CVS and it will be released once it compiles on FreeBSD.

Subject: SISC 1.9.0-alpha
X-URL: http://sisc.sourceforge.net/
SISC is a fast RnRS Scheme interpreter for Java. The alpha is the first
build with the full featureset for the next release. Users are invited
to download and test it.
The major architectural change is to "flat closures" from the "lexical rib
closures" of previous releases. A "flat closure" represents the entire
lexical environment. This makes closure creation more expensive, but means
that local variables can be kept in the interpreter and it removes a source
of memory leaking, so it should still come out ahead. There's more detail
on the sisc-devel mailing list and the srfi-40 discussion archive.
There are also "fixable procedures" and new library functions too.
Altogether, the authors think they can get within 30% of Kawa and
competitive with some C implementations.
