If every bit of your Python text conveys information, obviously, it
can't be abstracted. I don't believe that to be the case, though. So
this AST should contain all *actual* information worth conveying and
strip away irrelevant stuff.

Examples:

 * Function definition order.

 * Indentation depth.

 * Vertical empty space.


Of course, I'm not being completely serious about all this stuff because
the surface coding style questions are among the least relevant problems
in the code. But at least that kind of arrangement would free us from
the heated debates concerning the maximum line length etc.

(BTW, regardless of PEP8, the maximum line length *must* be 79, and the
maximum function length *must* be whatever can be seen on the screen at
once.)
