That's my preference, too. Have you ever tried GSLHaskell on MS
Windows? I do most of my work on Linux, but a guy I'm working with
uses MS, and I've heard cygwin can be a huge pain.

I have a big space leak right now I thought might be because of list
laziness in the interface, but that should be squashable with a little
work, and is not as big a deal as having lots of dependencies when
passing code around. I only really need one function from GSL, and the
odds of someone having written a work-alike in Haskell seemed pretty
good.

Of course, in cases where GSL is already installed, or where more of
its functionality is needed, GSLHaskell is the obvious choice.
