It's one of the things that Perl 5 is bad at. Not beacuse it can't do it, but because it's terribly terribly slow (compared with C) You don't want to write a linker in Perl. > For this esoteric sort of stuff can't we have named operators (short > names if you like, perhaps taken from assembly language), in a module > that can be loaded by those who need them? I think that we can learn from PHP here. :-) Nicholas Clark
