When implementing the internals of a computer algebra system you have to be careful because the "input" expressions might arrive indirectly. You have to think: what possible previous operations could have resulted in the situation I have now which is to evaluate 1**oo? There are many possible answers to that and they correspond to different final answers. In general using oo in expressions is not well defined if we don't specify how the limit should be taken but in certain cases the result is the same in any case. Otherwise as the zen of Python says: """ In the face of ambiguity, refuse the temptation to guess.
