In addition to STM, another item that should interest serious
programmers is forkIO. Lightweight threads that (unlike in Python)
can use multiple cpu's. Coming from Python, I personally appreciate
this. Using STM to handle concurrency issues often greatly
simplifies multithreaded code.
And further on this, the use of `par` in pure code to make it go
multicore is way beyond what most people think is possible.
I said _don't_ make me think of using par on a beowolf cluster of
ps3's. Don't you guys have any scruples?
Well... ghc still has a single-threaded garbage collector, so all the "par"
threads must stop for garbage collection. So scaling to the level of a cluster
would be significantly sub-linear.
