Boost QVM

mref

#include <boost/qvm/m.hpp>

namespace boost
{
    namespace qvm
    {
        //Only enabled if: is_m<A>::value
        template <class A>
        -unspecified-return-type- mref( A & a );
    }
}

Returns:

An identity view proxy of a; that is, it simply accesses the elements of a.

This allows calling overloaded operators when a is of built-in type, for example a plain old C array.
