12.4 Overloaded operators [over.oper]
12.4.4 Function call [over.call]
A function call operator function is a function named operator() that is a member function with an arbitrary number of parameters.
It may have default arguments.
For an expression of the form
postfix-expression ( expression-listopt )
where the postfix-expression is of class type, the operator function is selected by overload resolution ([over.call.object]).
If a surrogate call function is selected, let e be the result of invoking the corresponding conversion operator function on the postfix-expression;
the expression is interpreted as
e ( expression-listopt )
Otherwise, the expression is interpreted as
postfix-expression . operator () ( expression-listopt )
