If you want a fast language, try Holden. I've just invented it. 
Unfortunately it gets the answer to every problem wrong unless the 
answer is 42, but boy it runs quickly. The code for the whole 
interpreter (it's written in Python) follows:

print 42

Why are you looking for a "fast language" without any regard for the 
kind of problems you actually want (or need) to solve? Speed of 
execution is so insignificant for the majority of programming problems 
that this obsession reveals a certain inexperience.
