Of course.  That's why I think you ought to spell it 3//4.  Nobody gets
confused when a strange operator that they've never seen before does
something unusual.  Average Jo off the street looks at python code and
sees 3/4, and immediately thinks "aha! .75!"  Show the same person 3//4,
and she'll think, "A double slash?  I'd better check the
documentation--or better yet, play with it a little in the interactive
interpreter."
