But I've seen enough people write code that parses <...> reprs in some way to make me think that maybe they should be standardized somewhat, at least to the point where different Python implementations should not differ gratuitously. E.g. Jython could be much closer to CPython by inserting 'at 0x'. It's not like standardizing this would close off an important implementation freedom for other Python implementation. (I won't go as far as requiring that the number should be the same as hex(id(x)). :-)

I still think that depending on <...> reprs should be non-portable and discouraged, also CPython is already rather whimsical in its own evolution (Python 2.3):

class X: pass ... X <class __main__.X at 0x007E2C30> class X(object): pass ... X <class '__main__.X'>

I may change my opinion if someone writes a (unit) test pinning down what is exactly meant by that somewhat.

regards.
