Yes, I understand that.  But I spent many years in purgatory 
implementing
and using COM and Win32 interfaces, with lots of out and in/out 
parameters,
including doubly indirected pointers, and I just don't recall ever 
needing a
facility like this.  The problem you are working hard to solve just 
isn't
a problem in my experience, so I have zero willingness to clutter my 
code in
an attempt to solve it.  Your mileage may vary, as ever.

Anyway, I jumped into this thread mainly to opine that Noel's 
suggestions
were not, so far as I could see, any better than your proposal, not to
rehash what we have already discussed.
