Ben, much as I would like there to be a second kind of typealias, *typealiased
-- *that let us work with the renanamings wiithout risk to the objects of
the type originally aliased -- this is not on the radar now. It is hard to
peel off enough to form the CIGAR when the role of typealias is to preclude
introducing distictiction outside of recognizing a the alias as if it were
a nickname.
