5b590c9301 that seems to have got the type parsing right. (void []) () foo will work
and .float () foo works too

ddcaef5b0b that didn't work so well :/
back it out for now till I figure out how to get it parsing .float () foo
correctly

	o  generate an internal comipiler error for null opcodes rather than
	   segging.
