Also agreed, in theory. The language is definitely also in line with
this philosophy. In practice, though, it's also nice for low level
stuff to be fast right now. However, I expect that if the haskell RTS
gets implemented it'll be a switch at least until it's as fast or
faster than the C version, so it's all good.
Anyway, thanks for the clarification on the STM performance. I guess
it means I can't brag too much about pure performance, but there's
plenty else to brag about.
