Actually, D used to *have* the spaceship operator, and even several of
its friends like !<=, !>=, !<>=, and several others.

We deprecated them, and about a year or three ago finally got rid of
them.  Good riddance, I say.  Nobody uses them anyway, and nobody cares.
They are just a dead weight in the language, beautiful in theory but
never actually used in practice.

Don't bring those darned aliens back. ;-)
