I've said it before and I'll say it again: other imperative scripting languages feel like incomplete subsets of Perl. And the community is fantastic.

This is the language that doesn't have proper function arguments, exceptions, objects, etc, and you're calling OTHER languages a subset? Sorry, I just don't see it. What exactly is so awesome in Perl that isn't easily done in Python/Ruby/Scala/D/Haskell?

My claim that Python's syntax was going to be uglier is probably wrong, but I think the claim that Perl's is appreciably worse is also wrong. We can all get along!

        Exactly, it's a trade-off. Making the other side of the fence not impossible to reach, you just have to hop a little. Perl can easily be made nicer and Python can surely with ease be made more flexible.

        Not sure I follow you. Your python example is very explicitly passing a _single_ arguement, a list of three items. If you call it the same way you call the perl code, you'd have the same result.
