I would think that what we'd want to benchmark would be clean, optimized actually-used code. I.e. things like Data.Bytestring, so that we could see
so you propose to benchmark only low-level imperative code? :)
(correct me if i'm wrong, but everything fast i've seen, including FPS, is just imperative code)
I guess it depends what you mean by imperative, and I'll admit I haven't looked at Data.Bytestring's internals recently, but most of the code in FastPackedString (its predecessor) is just using a ForeignPtr as an array, which isn't imperative at all. Certainly it (almost?) never uses a mutable variable. So what do you mean by "imperative"? In any case, I meant code that *uses* Data.Bytestring, which is certainly purely functional. -- David Roundy Department of Physics Oregon State University
