[q-lang-users] Q 7.1 RC3 available

[Albert G. <Dr....@t-...>]

Hi all,

I've uploaded RC3 last night. (Needed to get some sleep first before I 
could do the announcement. ;-) There is a tarball as well as source and 
SuSE 10.0 rpms (I see whether I can make a Windows build later today). 
It's available here:
http://sourceforge.net/project/showfiles.php?group_id=96881&package_id=188958&release_id=416034

RC3 should be 99% feature-complete now, but the documentation still 
needs updating. There's lots of new stuff since the last RC; please 
check the release notes or the NEWS file for details. Most notable 
perhaps is the new builtin lambda and dramatic improvements in the 
performance of special forms in general and stream comprehensions in 
particular. The latter also benefit from the builtin lambda 
implementation. E.g., I found that the stream-based implementation of 
the 8 queens algorithm in queens.q, which used to be much slower than 
the imperative backtracking algorithm in queens2.q, is now just about as 
fast!

Here are some new and revised examples you might wish to take a look at 
if you're interested in lambda (I even got the normal order fixed point 
combinator to work) and streams:

http://q-lang.cvs.sourceforge.net/q-lang/q/examples/fixpt.q?revision=1.6
http://q-lang.cvs.sourceforge.net/q-lang/q/examples/streams.q?revision=1.2

I've also included Tim Haynes' latest cgi.q and Rob Hubbard's new 
rational.q (we'll probably see a separate announcement for the latter on 
the ML later today).

Tim, btw, it seems that your primetest.q example, which has been in cvs 
since 2004, never made it into the distribution tarball since I forgot 
to also include it in the Makefile.am's DISTFILES; that should be fixed now.

Peter, I wasn't able to fix the flex compatibility issue yet; I have it 
on my TODO list for 7.2 now.

Thanks to all for the helpful discussions and contributions!

Enjoy. :)

Albert
