> Well, depending on your problems, Haskell may simply not be the correct answer. It shines complex behavior for example, but "numerical work" normally means simple behavior (but highly optimized)

To give a rebuttal to Haskell not being good for "numerical work", you might be interested in this pre-alpha numerics library:

I'm tempted to agree with you re: low latency, then I run across stuff like this:

I believe it (or a similar library) are used in quite a few of a certain companies (or multiples) flagship applications, though I can't recall the details.
