Proposed resolution:
Change in 12.4.1 [over.oper.general] paragraph 7 as follows, removing the bullets:
An operator function shalleither
be a member function orbe a non-member function that hashave at least onenon-objectparameter or implicit object parameter whose type is a class, a reference to a class, an enumeration, or a reference to an enumeration.
(From submission #600.)
With the introduction of explicit object member functions, the restrictions on operator functions became inconsistent. Subclause 12.4.1 [over.oper.general] paragraph 7 specifies:
An operator function shall either
- be a member function or
- be a non-member function that has at least one non-object parameter whose type is a class, a reference to a class, an enumeration, or a reference to an enumeration.
Talking about non-object parameters in a bullet discussing non-member functions makes no sense. The following example ought to be prohibited, for consistency with operator==(int, int):
struct B { bool operator==(this int, int); operator int() const; };
