what is "substantial size"? can jhc be used for video codec, i.e. probably no extensions - just raw computations, and thousands or tens of thousands LOCs?
Perhaps. A bigger issue in practice is that the larger a program is, the more likely it is to depend on some library that depends on a ghc extension.
this is true for *application* code, but for codec you may have lots of code that just compute, compute, compute
Yes indeed. If there is code like this out there for haskell, I would love to add it as a test case for jhc. I don't see a reason it wouldn't compile to be as fast as C, with the caveat that the strictness analyzer needs to be able to find all the unboxables. It sometimes needs some help with well placed 'seq' statements, but that is true of ghc as well. jhc does suffer a lot more than ghc though when it can't make things strict.
