I'll have to investigate the 4x4 approach more closely.  For an FPGA,
2x2 cells may make sense, too (especially when you have cells with 3-4
inputs and 2 outputs that can route the bits either parallel or crossed).

Other things that may result in a speed-up:

	- separate sign extension from the right shifter
	- improve/rewrite stage 2 decoder
	- separate shift and rotate operations (beware! code duplication)

wtf is a "flying calf", and why does it need an optical output?

.o( pigs don't fly, so why should calves? )
