It's what I would do _when_ I am concerned about performance.  Fact
remains, there are string methods, and sufficiently many people like
them to make their disappearance a great disappointment.

That's far too much trouble for a convenience.

It isn't possible for a language to provide every convenience, and
remain sane, lean and fast.  If all strings could have their own
metatable, it would drag down everyone's code for the sake of
something that's really very specialized.  So I remain a fan of PUC
Rio's engineering style - slowly, surely - and ignore fads.
