Does that work for an array-based storage policy adding operator[] (if
there is no conversion to T* operator)? And then for both non-array and
array if there is a T* conversion?
I know I should be able to answer that from knowledge of language rules,
but it is past my bed time and my mind shut down awhile ago.
I would have trouble accepting that a smart point really supported arrays
if it couldn't supply the usual [] notation.
OTOH, we aren't talking about an unbounded list. So if private inheritance
is really better, maybe there is a way to wiggle around the need for the
two operators in question.
