Subject: [Boost-users] reference_wrapper 101

I thought understood what boost::reference_wrapper was all about, and in the
of, say Boost.Bind, it seems pretty clear.
But why would you define a function to RETURN a reference_wrapper? eg
template <class T> struct X
std::pair<boost::reference_wrapper<T>, unsigned> getSomething(....)
I suspect I'm having a 'doh' moment here!
