"PySlice" with karma 25 is probably your trolling account. If not, ASK about stuff you have no clue about. It is better than looking like a little troll kid, having "fun" lowering the quality of HN by stupid language war comments.

That is optional, through the power of CPAN (and kbenson's methods, of course). Examples of alternatives:

http://search.cpan.org/~flora/MooseX-Declare-0.35/lib/MooseX...

http://search.cpan.org/~ether/MooseX-Method-Signatures-0.44/...

(Depending on if you use Moose or not.)

"the" language is then more of a loosely couples family of languages.

Not half as much as any Lisp variant with good macros.

Edit: The possibility to extend your environment is generally seen as a good thing, unless you believe in cleanliness of bloo... languages for ideological reasons.
