> amount of work required to do this is much much more than amount of work required to write optimal C/asm code
I'm sorry, but no it's not. I've been using Haskell for a little under two years now, and I'm already able to produce programs with significantly less pain which outperform the C equivalents. Sure, if I pour a lot more time and head scratching into my C, then I can probably beat my Haskell, but I just don't have the time (or the need) to introduce pointer tagging, lazy evaluation, and referential transparency transparency to my C code. Any way, this thread has lost any usefulness.
