There are at least 2 posts a month by someone who decides that they
want to re-wire Python syntax. Usually it's because of some particular
idiom they're used to in another language, in other cases it's because
they've got some particular issue with "consistency". The ideas are
*never* fully thought out or materialized, and they invariably invite
scorn from the user community. The poster is almost always a Python
beginner (I don't know if thats true in your case or not).
Arbitrary changes to syntax are never going to fly. It's a lost cause.
If you can't handle Python without your pet changes, fork it and write
your own version and let the marketplace of ideas decide if its
useful.
