Re: a new version of perl for Windows

I think that there will be some incompatibilities for some modules, especially those who use C code, and that's why I haven't tried it for the moment.
I am almost sure that there will be some issues regarding mod_perl and maybe WxPerl also, so I prefer to wait a little.

Thanks for that news, Octavian.

Do you know whether most existing Perl libraries will be compatible with
the new version, or in general, should one wait until a library
specifically says it is compatible?  Also, I'm curious what benefits you
personally find in the new version.

Subject: a new version of perl for Windows

Perl 5.10.0 has been released today, the first in the 5.10.x major
version series, after a five year long development process.
Coincidentally today is also the 20th anniversary of the very first
release of Perl 1 to the public.

----------------------------------------------------------------------

ActiveState is pleased to announce ActivePerl 5.10.0 Build 1001, a
complete, ready-to-install Perl distribution for Windows, Mac OS X,
Linux, Solaris, and AIX.

This build is based on the release version of Perl 5.10.0.

For detailed information or to download this release, see:

New in ActivePerl 5.10.0 Build 1001
===================================

Some exciting new features to look for:

* The new switch statement and smart-match operator

  The new smart-matching operator ~~ compares two expressions with each
other; the exact nature of the match is being determined by the types of 
  both expressions: matching a string and hash will return if the hash
  contains a key equal to the string; matching a regular expression
  against an array will return if any element of the array matched
  successfully against the regexp etc.
The new switch statement will smart-match a single expression repeatedly 
  against a list of other expression until one matches. For example:

    given($foo) {
        when ("foo") {
            say '$foo is the string "foo"';
        }
        when ([1,3,5,7,9]) {
            say '$foo is an odd digit';
            continue; # Fall through
        }
        when ($_ < 100) {
            say '$foo is numerically less than 100';
        }
        default {
            die q(I don't know what to do with $foo);
        }
    }

* Defined-or operator

  The new defined-or operator // allows you to write

    $a // $b

  instead of repeating the first argument as in

    defined $a ? $a : $b

  Also the statement

    $c //= $d;

  can now be used instead of

    $c = $d unless defined $c;

* Many improvements to the regular expression engine, including:

  The regular expression engine is no longer recursive, meaning that
  patterns that used to overflow the stack will either die with useful
  explanations, or run to completion, which, since they were able to blow
  the stack before, will likely take a very long time to happen.

  - It is now possible to write recursive patterns that are easy to read
    (for a regular expression), and are executed in an efficient manner.

  - It is now possible to name capturing parenthesis in a pattern and
    refer to the captured contents by name. The naming syntax is
    (?<NAME>....). It's possible to backreference to a named buffer with
    the \k<NAME> syntax. After the match the named capture groups are
    accessible via the %+ hash:

        my $value = "foo 42";
        if ($value =~ /^(?<name>\w+) \s* (?<number>\d+)$/x) {
            say "Name $+{name} and Number $+{number}";
        }

  - possessive quantifiers
  - backtracking control verbs
  - relative backreferences

Other new features include:

* new say() function
* lexical $_ variable
* _ prototype
* UNITCHECK blocks
* state variables
* stacked filetest operators
* byte-order modifiers for pack() and unpack()

* Many bug fixes
* Additional core modules
* Extended documentation
