APL is fairly obsolete now anyway.  A more modern version of that language is J (www.jsoftware.com), 
which does not use special characters.  I've studied the language a bit, and it's quite interesting, 
but it really doesn't offer much (anything?) over Haskell except a much terser notation and simpler 
mutable array support.  I'd stick to Haskell.
