[q-lang-users] Q 7.8 RC1 is out

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

Grab it while it's hot... here:
http://sourceforge.net/project/showfiles.php?group_id=96881&package_id=188958&release_id=544135

Special acknowledgements this time go to John Cowan, Alexander Nickolsky
and Eddie Rucker for reporting bugs, contributing examples and
suggesting improvements. Thanks guys!

Here's a brief overview of the most important changes in this release:

- Lots of bugfixes (most notably, the annoying 'where' bug found by
Eddie has been fixed, and a couple of obscure segfaults in the bytecode
compiler, too).

- Qualified import clauses ("from module import ...").

- Slim prelude (stdtypes.q and POSIX interface not in the prelude anymore).

- New tuple and string operations. Tuple enumerations and comprehensions
are now supported, as well as cat, map, do, dowith, dowith3, reverse on
tuples (cf. tuple.q), and all the stdlib.q list operations now work on
strings, too (cf. string.q).

- Special support for mutable containers, as recently discussed here;
see reftypes.q. (2D sequences and indexed containers like array and dict
now work, too.)

- Various improvements in compiler and interpreter (better diagnostics,
new whois command, ...).

- Updated documentation. For the new features, check in particular
Chapter 4 and Sections 11.2, 11.3 and 12.14. Appendices B.1, B.2 and B.4
might also worth taking a look at. The q.1 manpage has had an overhaul, too.

The only known backward compatibility issues are due to the new slim
prelude. You are kindly asked to check your scripts with -w to see
whether any of the following explicit imports may be needed with the new
version: getopt.q, stdtypes.q, system.q.

As usual, please check the NEWS file and the ChangeLog for details. And
please report any issues building the new version, or other bugs asap.

Enjoy! :)
Albert
