Lambda the Ultimate

Programming. Programming languages: mostly Functional and Logic related, but I love learning new languages of any type. My favorite languages include (listed alphabetically): Erlang, Haskell, Prolog, Scheme, and Standard ML.

Other more obscure (but perhaps even more interesting) languages which I follow casually are (which I will sadly never likely have the opportunity to write an application in due to to their tiny communities) Alice ML, Oz/Mozart, Mercury, Ur, Kanren, and a few others. Sadly, Standard ML probably belongs in this list as well, due to its diminishing community.
