I picture $add->(1) cloning add's optree, filling in the 1 where
appropriate, then returning a reference to the new (cloned) optree.
What to do with private variables (and the possible stack of private
variable bindings that goes with recursion) is something I can't
see my way through.

When there are no more language objections to this, I say we throw
it over to the -internals group to pick at.  It is quite a meaty
bone.
