__inherit
If (i) `lhs` of type `Lhs` and `rhs` of type `Rhs` can be used in expression `lhs/rhs`,
and (ii) `Ret=dont_care` or the result of expression `lhs/rhs` is convertible to `Ret`
then inherits from __true_type,
otherwise inherits from __false_type.

The default behaviour (`Ret=dont_care`) is to not check for the return value of binary `operator/`.
If `Ret` is different from the default `dont_care` type, the return value is checked to be convertible to `Ret`.
Convertible to `Ret` means that the return value of the operator can be used as argument to a function expecting `Ret`:
``
void f(Ret);
Lhs lhs;
Rhs rhs;
f(lhs/rhs); // is valid if has_divides<Lhs, Rhs, Ret>::value==true
``
If `Ret=void`, the return type is checked to be exactly `void`.
