I'm aware of the existence of this class. As long as it's only an 
implementation detail of a library it's not of much help to library users,

Sure, but it would be nice if such a thing would be publicly available in 
Boost, just using the generalized bind approach. I believe it would fit in 
nicely within the ScopeExit library, as long as it isn't called 
"scope_guard" ...
