Python.

What's bad about Python?

If you need an extension language for your C application,

I'd rather write my own DSL ``in Lisp'' for that purpose. Hell, I could come up with a better Lua that has a ``lightweight'' interpreter and isn't painfully slow in about 3 days.

with LuaJIT for speeds that Python can only dream of

There's PyPy too. That's not a valid point.

But I get what you're trying to say. Some people are too busy trying to churn out EPIC CODES as quickly as they can and that's where Python, Lua and (to a certain extent) Go are actually useful.
