Hi,

I'd like to use BOOST_RV_REF, with both C++98 and C++11 compilers, for some sink-functions, with types that are not "move-enabled". I.e. types that the sink can "consume"/"move from" by other means (swapping, calling .release(), ...). Some of them I can - eventually - change to be fully move-enabled, others I can not (e.g. STL classes).

I just assumed that this was possible by simply passing the argument with boost::move(arg). Apparently it's not though, because boost::move will return a plain T& for types without move emulation.
For the time being I have defined my own helper function template "move_any" that will always return a rv<T>&.

Is there such a function that I missed? And if not, would you think it'd make sense to provide one (I certainly think it would)?

Regards,
