A thread like this just came up on the Tutor list.  Remember one of
Python's goals is to allow people to produce naturally looking source
code, and "x is y" is just a natural thing to write.  Especially for new
programmers who might not have much of a clue of how objects are dealt
with internally.

I don't really see a difference.  "is" can only be used in the one sense
anyhow, so it acts as a constant alias for "id(x) == id(y)".  Given this
there's not really a chance that anybody could confuse it with anything
else.

Anyhow, just wanted to offer another POV on this.  Sorry for being
off-topic.  :-)
