Your sort method isn't really what most people would consider functional 
programming, being that it relies on mutating the array (and the each-method 
which isn't even present in purely functional languages being that it needs 
side-effects to have any effect at all).
If you want to implement a sort method in functional style, you should 
consider doing a recursive quick sort, which is quite simple and can be done 
in one line if you don't count the "def foo()" and "end" as their own lines.
Also functional programming does not equal "one line". There's nothing wrong 
with spreading it out over multiple lines for readability.

HTH,
