Additionally, I'm concerned that doing this in talloc (rather than in
local macros with clear purpose) may be confusing with regards to the
talloc tree.  This new talloc object would be a duplicate in name, and
in memory, but would not have duplicate children - which if this is a
struct, may be pointer elements in that struct.
