The perfect language

I'm searching for a language to explore the unknown. I therefore don't know what I'm really going to need.

Here are some languages I already tried out:

C
C++
Java
Perl
Python
Haskell
Delphi
Common Lisp/Scheme

Here are some languages I feel like trying out:

Ocaml
Prolog

Here are some of my requirements:

- multi-paradigm including object oriented and functional
- good linux support
- short and sweet (sort of like perl and haskell but not like lisps) for rapid prototyping
- well documented/supported
