I think Concepts somehow help here. By using a concept to check whether
a type has given member functions or operators with given signatures,
and overloading the piece of code without a concept to be the fallback
code, you get similar things.

Also, you could provide some compile-time reflection to check whether an
expression is valid or not.

Such as duck typing?
