It would be nice if we let the compiler discover all of the possible
vectorisations possible.  I've got no idea what the current state
of the art is in this respect, however I would imagine that it would
still be -cheaper- to build a simple compiler that took hints or 
directions from the programmer about possible vectorisation.

Does anyone have real info instead of my speculation?
