Your answer of an equal() function doesn't help with sets and dicts either.

So I guess we're stuck with no good standard answer:

- the easy two-line function doesn't even come close to solving the problem
  of case-insensitive string operations;

- but we can't have case-insensitive string operations because too many 
  people say "just use this two-line function".
