Someone told me once, that programmers tend to learn one scripting language properly and ignore or dislike other scripting languages. Do you have similar experiences?
 I'm using Python as my choice for scripting for  few years, however, I'm sure that there are many existing and emerging languages that could impress the Pythonistas. Can you recommend scripting languages that would be interesting and useful to learn besides of Python?
Ruby - what it enables and does with blocks is really interesting, and quite foreign to python based programming
Erlang - the functional language has a lot of interesting examples and it will definitely make your head work differently afterwards (in a good way)
Javascript - yes, I'm serious. ALthough there's a fair number of grips to be had with this prototype language, it does some really interesting things with that prototyping and just slightly differently than Ruby and/or Python. And a ton of folks are pouring big money into making Javascript a outstandingly fast scripting language.
