The purpose is to make usage of the operator module more readable, particularly
for some of the more exotic operators. For instance, I find
``operator.get_op(">>=")`` to be a lot more obvious about what's going to
happen than ``operator.irshift``.
Also, I think it is helpful to have available a listing of all the operators
that Python supports. If we're going to have such a listing, why not make it a
mapping of op to function? And once we have such a mapping, it would be nice
to have a nice interface to it.
Having this available would make it easy to implement the kind of function that
Nick mentioned in the python-ideas thread, that takes an operator string
instead of only a function.
I will admit that the need is not great, and obviously this isn't something
that someone who needs it couldn't do themselves. But I think the convenience
of it makes it at least worth consideration.
