Are you suggesting that this should be done on the fly
when comparing strings? Or that all strings should be
stored in canonicalised form?

I can see some big cans of worms being opened up by
either approach. Surprising results could include
things like s1 == s2 but len(s1) <> len(s2), or
len(s1 + s2) <> len(s1) + len(s2).
