    Announce: Rakudo Perl 6 compiler development release #53 ("Strasbourg")

On behalf of the Rakudo development team, I'm glad to announce the
June 2012 release of Rakudo Perl #53 "Strasbourg". Rakudo is an
implementation of Perl 6 on the Parrot Virtual Machine (see 
<http://www.parrot.org>). The tarball for this release
is available from <http://github.com/rakudo/rakudo/downloads>.

Please note: This announcement is not for the Rakudo Star
distribution[*] -- it's announcing a new release of the compiler only.
For the latest Rakudo Star release, see
<http://github.com/rakudo/star/downloads>.

The Rakudo Perl compiler follows a monthly release cycle, with each
release named after a Perl Mongers group. The June 2012 release is
code named after Strasbourg, the location of the French Perl Workshop 2012.

This release includes a lot of changes since the last one, including:

* Longest-Token Matching for | alternations in regexes
* Stricter numification of strings (fails if the string does not
  represent a number)
* 'require' now allows argument lists
* Faster .map / list handling
* Improvements to typed exceptions

This is only a small peek at the changes in this release. For a more
detailed list, see "docs/ChangeLog".

The development team thanks all of our contributors and sponsors for
making Rakudo Perl possible, as well as those people who worked on 
Parrot, the Perl 6 test suite and the specification.

The following people contributed to this release:

Contributors to Rakudo since the release on 2012-05-17:

If you would like to contribute, see <http://rakudo.org/how-to-help>,
ask on the perl6-compiler@perl.org mailing list, or ask on IRC #perl6
on freenode.

The next release of Rakudo (#54) is scheduled for July 19, 2012. A
list of the other planned release dates and code names for 2012 is
available in the "docs/release_guide.pod" file. In general, Rakudo
development releases are scheduled to occur soon after each Parrot
monthly release. Parrot releases the third Tuesday of each month.

On behalf of the development team, I encourage you to try the new release.
Have fun, and let us know about your experience.

[*] What's the difference between the Rakudo compiler and the Rakudo
    Star distribution?  

    The Rakudo compiler is a compiler for the Perl 6 language.
    Nothing else.

    The Rakudo Star distribution is the Rakudo compiler plus a selection
    of useful Perl 6 modules, the most recent incarnation of the "Using
    Perl 6" book, and other software that can be used with the Rakudo
    compiler to enhance its utility.  Rakudo Star is meant for early
    adopters who wish to explore what's possible with Rakudo Perl 6 and
    provide feedback on what works, what doesn't, and what else they
    would like to see included in the distribution.
