This isn't talking about your Python code as much as about Python
itself. For example, in Python 2.x you can use either `open` or `file`
to open a file, with `file` being a factory function for creating file
objects, and `open` using it internally. In Python 3.x, `file` is no
longer a built-in, as it produced a point of confusion as to which was
the one obvious way to open a file.

It's better to not add a language feature than it is to add it poorly,
especially when you endeavour to provide backwards compatibility as
much as possible within major versions.
