I think this begs the question then, what is the necessity for an Arity parameter as part of the definition of an expr<>?
According to:

it's use for specialization. In my reply to that post I suggested maybe a helper template to eliminate the need for this 3ird parameter, but then, AFAICT, this just delays the need for a 3 parameter expr...but wait, if some how the 2 parameter expr were public and somehow the 3 parameter were made private, maybe that would be better.
Well, since expr is an aggregate, adding an extra layer of indirection would change the interface, so I don't think that would work. In Christ, Steven Watanabe
