[over.ass] (13.5.3) states "An assignment operator shall be implemented
by a non-static member function with exactly one parameter."

Is the intent of clause 13.5.3 to apply to all assignment operators (=,
+=, *=, etc), or to only the simple assignment operator (operator=)?
The wording and examples in 13.5.3 imply the latter, but a strict
interpretation would apply it to the former, which would disqualify
functions such as:

class T
{
//...
friend float operator +=(float &f, T&);
};

I would suggest that 13.5.3 be re-worded as follows:

"1. A simple assignment operator ..."

"2. Any simple assignment operator ..."

Similarly in [class.copy] (12.8) the Note in paragraph 9 should be
amended to read:
"Note: an overloaded simple assignment operator must be declared to have
only one parameter; see 13.5.3."
