I entirely agree with Alex that the subliminal message of "<>" has
gotten much worse in 2.1.  OTOH, I really can't see how to construe the
loss of universal inequality operators as a good thing.  I'm starting to
believe it a sin on the order of "print >> file" :-(.  Spelling is just
spelling, of course, but some spelling is better than other spelling (as
the Orwell thread reminds one).

However--hopefully not belaboring the point--my problem with "!=" is
that it contains much stronger subliminal misinformation, even still,
than "<>" does.  "!=" just plain LOOKS like it should be an augmented
assignment.  Admittedly, *this* only "broke" in 2.0.  But I think I can
make a strong argument that there are more users of 2.0+ than there are
of 2.1+.
