Yes, Parrot is a April Fools prank. See Simon's article on it at O'Reilly's site.
Having said that...Inline::Python lets you run Python code directly in your Perl. Much MUCH worse is Language::Pythonesque, which allows you to do something sorta like Python source into Perl (a little bit, anyway...) because Damian Conway's a sick bastard.
Glad he's on our side. :)
Also, it's been mentioned by Larry that Perl 6 will be able to take other syntaxes (like Microsoft's .NET and the like) and convert them into Perl 6 "code":
First, Perl will support multiple syntaxes that map onto a single semantic model. Second, that single semantic model will in turn map to multiple platforms.This is something that's being done now, as shown by Damian.
If all the above hasn't blown your mind, this last bit from Damian's diary (whihc I highly recommed!) should do:
And, yes, eventually there will be a complete Perl-in-Klingon module: Lingua::tlhIngan::yIghun. The really scary part is that, based on my previous experience with Lingua::Romana::Perligata, Coy, and Quantum::Superpositions, I am certain that somewhere out there is someone who will actually use it.
