Haskell is nice for what it is, but I wouldn't really call it a
practical language, simply because, last time I checked, performance
wasn't very good, and it didn't have much in the way of libraries. But
it is very elegant syntactically.

Erlang (http://www.erlang.org) is, I think, a better choice for real
work. It is also a functional language, but with built-in concurrency
using asynchronous messages to pass data between processes which may
live on the same machine or on other machines reachable via a network.
Ericsson has used it in a number of significant projects, including a

Erlang is not only free software, but it's already packaged for Debian
(though I think it's been orphaned; it's in stable, but no longer in
testing or unstable).
