covered reasons for leaving shared_ptr's as they are -- I don't support the
viewpoint that shared_ptr should have two ->/* functions).  But I use
scoped_ptr's to hold the pointers to a private implementation struct.  When
I do this, I don't want to have non-const access to the struct in const
functions.   Having a scoped_ptr<T const> won't help me in this regard
because I do want non-const access in non-const functions.

Ah.

Thanks, I understand now.
