Pythonising the vim (e.g. syntax popups)

[Lonnie Princehouse]

There is a Python folding script, as someone already mentioned.  That
will help you track indentation, although it's not perfect (iirc, long
triple quoted strings cause folding malfunctions)

I don't know of any way to get dynamic help about functions, although
it seems like an ideal use of Vim's built-in Python interpreter and the
vim python module.
