[ or ] Python.
I guess it depends on what you want to do.
That it does and each language has its "specialty".
Perl is perhaps a bit out-of-date compared to Ruby and Python.
I would definitely not say that. First, Perl still has the most powerful Regular Expression engine of any other language. Plus, have you seen the advancements in Perl 6? The language may seem "out-of-date" to some, but it is current and quite the contender.
