Maybe this is also a good time to start distinguishing between arguments (what you pass, call syntax) and parameters (what the function receives, function definition syntax)?
The glossary is one place to start making this distinction. It currently has entries for "argument," "positional argument," and "keyword argument" that could perhaps use a review from this discussion. For example: http://docs.python.org/dev/glossary.html#term-positional-argument The entries currently blur the distinction between the calling and definition perspectives. Ideally, the glossary definitions of these terms would match and be consistent with their usage in error messages. --Chris
