Looking at the code, it seems boost::bind uses non-const reference for
operator() -- the actual forwarding -- and by-value for arguments to 'bind'
So, you should add pass by non-const reference to the list of alternatives.
What I think about it is that const-reference prevents you from passing
non-const references to constructors of objects you put to container. OTOH,
with non-const references you'd break the passing of integer literals --
which is the point of the library.
Maybe, you really should support ref<> for passing non-const references.
