I like the Idea but i dont think microsoft was the first to think of a runtime that you could stick other code into in.The new perl 6 will have the built in as wel,l and it has been said that the developers of perl 6 came up with the Idea first....But I think if your in a windows world and you want to stay then get it...but I can make wiget's that will work in windows a linux with out changing Languages.Like this

Code:
#!/usr/bin/perl
#!c:\perl\bin\perl.exe

use Tk;

$mw = MainWindow->new(-title => 'Perl\\Tk ');
$mw->Label(-text => "This is a App Made with Perl and Tk")->pack;
$mw->Button(-text => 'Exit', -command => sub {exit})->pack(-side => 'bottom');
MainLoop;
this will run with no mods on my linux box and windows box.
