General Development Version 6 of the popular Perl programming language will not be compatible with previous versions, but will open up a new world of custom "languages" and interpreters, according to its founder Larry Wall. Wall and his co-developers are doing with Perl 6 -- starting again. "It will break backward compatibility [but] in order to simplify it we have to get rid of old cruft, particularly the regular expression cruft," Wall said. "A lot of the unreadability of Perl is related to the regular expression syntax " and we didn't do that, we got it from Unix. It needs to be end-of-lifed."

Porting to Parrot virtual machine benefits:
* primary designed for dynamic programming languages
* register based VM, great potential
* interoperability provided at an assembly
level
* open source, platform agnostic
* many features for free PCT, PGE, embeding, mod_parrot, ...

"Parrot is innovative and not just a .NET or
JVM clone.", Jonathan Worthington, 2005

"Perl 5 has two big features that make using the JVM or .NET problematic--closures and polymorphic scalars. Perl 6 adds a third (which Ruby shares) in continuations, and a fourth (which Ruby doesn't) of co-routines." Dan Sugalski, March 25, 2003
