* is it sufficient to return the value of the key object's id()
function to produce a perfect hash?
* when might it be useful to consider keying by identity?
* what are the limitations of programming this way?
Thanks!

Hi Peter,
Thanks, that does seem to indicate something.

the documentation of __hash__ could fix the problem.
Is that too much to hope for? How would I proceed to get somebody to
look at this?
Thanks!

__hash__ (in the implementations of Python I have tested).
Please try the code yourself. Tell me what I am missing.
What "other problems"? Please provide an example!
Thanks!

Hi,
I have an application that would benefit from object instances
distinguished by identity being used in dict's and set's. To do this,
the __hash__ method must be overridden, the obvious return value being
the instance's id.
This works flawlessly in extensive tests on several platforms, and on
