(Probably this is a very naive comment. Anyway..) I've dabbled in some FPish languages, most lately Prolog (which I loved) and ML. I do a lot of graphics programming, so was wondering how to do that with ML. Like say you have an 3D array representing colour pixels, and want to change a pixel's colour. It seems in FP either you make a new copy of the whole updated array, or use fiddly workarounds where you store the changes and actually do them at some later time.. Googling about it, I felt quite embarrassed for FP, since all the talks I'd seen present it as a mega-cool super-sophisticated best way of doing everything. And as if changing variable values is a barbaric sin. ..So, back to C to do graphics. Situations like this, where large data structures must be repeatedly changed in small ways, which happens in a lot of domains I guess, seem tricky to do efficiently with FP!
