[Python-ideas] π = math.pi

[David Mertz]

This is a horrible thing that nobody else should do :-), but I *am* the
author of the file linked by Pavol.  It's based on someone else's version
(credited in the file), but I fine tuned it for what I want.  I'm also not
the author of the conceal plugin for vim, which is pretty much exactly for
just this.

The screenshot attached is a little bit of a vim session editing a Python
file.  The key thing is that I *type* only regular ASCII characters; I just
tell vim to show my something different on lines I am not currently editing.
