I don't find Steven's example convincing. Sure it can be used in a way
that damages readability considerably however lots of things in python
can be abused in a way that damages readability considerably.

That you are not interested in having to maintain someone's code who
would use such symbols is irrelevant. IIRC people have used the exact
same kind of argument against decorators and the if-else operator.

It seems we are all consenting adults until someone doesn't like the
idea how it might influence his job. In that case it shouldn't be
allowed.
