I concur with Raymond. Doctest should test the representation, not value.

But I think it would be nice to support insignificant variations of the representation. Tracebacks already are treated specially, and different doctest options allow to ignore particular details. Of course ignoring the whole content of the dictionary will be not very useful.

   >>> dict_fun() # doctest: +ELLIPSIS
   {...}

But maybe some option should make accepting some permutations in the output. E.g.

   >>> dict_fun() # doctest: +PERMUTATION
   {<'foo': 1>, <'bar': 2>}

should accept both "{'foo': 1, 'bar': 2}" and "{'bar': 2, 'foo': 1}".
