I have decided to escape the world of Perl into something more definitional. I gave up on CAML and Erlang because they contain imperative elements and I am tired of that form of coding. So, I have narrowed it down to Haskell and Mercury.

That page really only describes the differences in the type systems.
A very important distinction between Mercury and Haskell which that page
just skims over is that Haskell is lazy by default, and Mercury is not.
