??? I've multiple inheritance to use, "so have many C++ programmers,
some of which have moved to D."
By useless I meant that it can be replaced by if/else, so it does not
fill in a void.

Just as slow as if/else:
asm {
cmp x,y
jne l1
nop ;case one
jmp l2
l1:
nop ;case two
l2:
}
It'll always jump.

The if would be more readable. I find it "unreadable", mostly because
there's not really a limit to what you put between ? and :..
I agree it's handy now and then, but I really would like it to be
limited to constants or something.
