[Python-ideas] π = math.pi

[Stephan Houben]

I use the conceal feature for this purpose,
but I use

https://github.com/ehamberg/vim-cute-python

instead, which is a more toned-down version of the same idea.

I personally find
  x ≤ y, a ∉ B
more readable than
  x <= y, a not in B
etc.

Especially the conceal
lambda => λ
is useful for de-cluttering the code.
