Not on the horizon, it's too difficult. The best effort I know of
automatically introduces par to the code /after running/ the program a few
times (with the same given input data). There was some paper somewhere
describing the idea and what the results were (IIRC, they achieved a
respectable speedup in cases where there was enough potential for
parallelization). Note this is /not/ something a compiler could do.
