Python Library Reference is tutorial, not reference

Current Python documentation describes the functionality of each
function and method. Pydoc gives you APIs and the docstring if one is
The only place you are likely to discover rationale is in the source
code itself. The code for sorting lists has great rationale as for why
Python uses 'Timsort', and not another algorithm.
What it seems like you are suggesting is that the API reference should
get copies of "why we do this here" as listed in the source code. While
it would be interesting, I am not sure it should necessarily be a part
of the documentation (especially API documentation). People read
documentation because they want to learn how to use something; those
that really want to understand the internals, and why it was designed
and built the way it was, go to the source.

Give it a shot, you may be surprised.
