[$] Python identifiers, PEP 8, and consistency

While there are few rules on the names of variables, classes, functions,
and so on (i.e. identifiers) in the Python language, there are some
guidelines on how those things should be named. But, of course, those
guidelines were not always followed in
the standard library, especially in the early years of the project. A
suggestion to add aliases to the standard library for
identifiers that do not follow the guidelines seems highly unlikely to go
anywhere, but it led to an interesting
discussion on the python-ideas mailing list.
