I do this all the time (but using a scope guard), for globals I've 
declared thread-local.  This essentially simulates dynamic scoping 
(which I'd prefer to see supported directly by the language, as an 
alternative to lexical scoping).  Perhaps a Boost library for 
dynamically scoped properties would be nice?
