There's a second part the mystery - sets and dictionaries (and I think
lists) assume that identify implies equality (hence the second result). This
was recently discussed on python-dev, and the decision was to leave things
as-is.

Scenario: a file-name from potentially untrusted sources may have
odd filenames that need to be sanitized for the underlying OS.
On *nix, this generally just means "don't use '/' or \x00 in your
string", while on Win32, there are a host of verboten characters
and file-names. Then there's also
time = get_fields()
date = datetime.datetime.fromordinal( date.toordinal() )
