Having been burnt by such C++ code, I have to agree.  Makes us
grateful that the Lua authors are such conservative engineers, in the
good sense of the word.

But, as Mark says, it closes a gap: array-like objects can now
delegate their implementation. Any decent language has features which
are meant to be used by framework builders, who are assumed to
intelligent _and_ sensible. This may be a rather strong condition ;)

An interesting question would be: how do we know when we've arrived?
What are we currently struggling to say, that cannot be said clearly?
