Another problem with this is that it uses punctuation in a manner
that's neither similar to how it is used in written English (or Dutch,
or any other Latin language) nor resembling of other areas in Python.
I know this is a very strict constraint, and sometimes we violate it
(@decorators come to mind) but still, as a general guideline, if it
can be avoided, using punctuation in new and strange ways just isn't
Pythonic. That also applies to using ';' but not (at least not so
strongly) to '*' (since that can easily be seen as "*args without the
args").
