The tab completion is a good point, I did not think about that. In the
one function case the possible modes would be listed in its docstring
only. But one has to read docstrings anyway (well, sometimes :)) and all
the related functionality would be in one place which is IMHO good. Just
my 2 cents.
I would like to hear some feedback to my original naming style question,
as I face same issues in my projects too. The question is about using
function names that mix underscores with capital letters, e.g.
solve_P(). This style is marked "bad" in the Python docs, but in linear
algebra, matrices are commonly denoted by capital letters. So what do you
