This is actually an interesting issue when you're working with Python
interpreters. For example, an object with a simple repr() which is code
to create an identical object is easy to use as a key in a dictionary.
I ran into this a while back when I was tinkering with IDLE's
auto-completion module, and ended up writing some code which checks if
an object's repr() is "reversible" or not.
- Tal
reduce(lambda m,x:[m[i]+s[-1] for i,s in enumerate(sorted(m))],
[[chr(154-ord(c)) for c in '.&-&,l.Z95193+179-']]*18)[3]
