There may be other important patterns to address at the core, please

Another case is when you want to distinguish between lvalues and rvalues.
Good one. This is in fact what happened in C++: const T& binds so
tightly to T rvalues, that it was impossible to work a wedge in between
to allow overloading on T and on const T&. Therefore, a much heavier
solution was needed.
