Actually, Ruby allows this notation and, until now, I have not seen many
complains about it.
Despite that, its use would be pretty clear for the beginner, since it would
be associated with meaningful identifiers:


The worst problem could be the useless parenthesis after the '?' sign.

 IMHO, IPython might not be mature enough to interfere with Python design
decisions yet.
