Beginning functional programming

[pjt <pt720185@gmail.com>]

Hi all - 3rd year student at West Chester University here, hoping to
get started learning functional programming. I'm attracted to the idea
of no side effects, as well as the close relation of functional
languages to mathematical ideas and notation. I'm wondering, what is a
good language to start with? I've heard good things about Haskell and
Clojure, but I'm hoping to get some more opinions.
Thanks.
