(expression-list)// the postfix-expression must be the name of a function (amongst some other// choices). This means comma and conditional exprs cannot be placed there.// This clause is the only one I can find which bans//  (cond ? fna : fnb) (arglist)// which would be a major headache to have to implement.// [over.over] 13.4 tells us when the use of a function name w/o arguments is// resolved to the address of a particular function. These are determined by// the context of the function name, and it does allow more complicated primary// expressions.// Using a naked function name is rather strange, we used to warn about it// (rather inconsistently), but subsequent changes broke the warning.
