Provided 'something' is a string, that should be true, as should the
simpler statement a == eval(repr(a)) (since '%r' is just a more complex
way of getting the same thing as repr()).

On the other hand, if 'something' is actually some arbitrary object,
then it's definitely not always true, especially for anything not built
in to Python.
