The trouble is that the beta->ptf() is a bit difficult to parse. There's a 
lot going on there trying to figure out what the user intended.
It may not seem so on the surface, but in trying to work that into
the parser, I thank Bjarne for those extra parens!

P.S. I always thought the ability to dereference a function pointer by
the shorthand method (no *) was a botch in the language. If you are dead
set about how convenient it is, try:
	#define func (*func)
Ah well, all water under the bridge!

P.P.S. I also think the address of func should be written as &func. Seems
clear to me!
