I rather like the discussion in [How do I write a function with output parameters].  Some variant of each of those solutions arise in code reviews over and over again.  Rarely do the occur in simplistic examples, but they do occur.  The simple examples given are the easiest way to learn about the anti-patterns.

In the section [How do I use strings to call functions/methods?], let's eliminate the eval() variant which isn't really helpful.  The locals() technique does occur in practice and is worth showing.

In the section [How can I sort one list by values from another list], I concur that we can completely eliminate "alternative" and its explanatory text.
