That's a great idea Carl! You mean something like this:
int sum(int a, int b) {
if( argc == 1 ) b = 1; //default for b if not supplied
return a + b;
}
//...
auto f = ∑
//...
auto x = sum(y); //function pointer call, so fewer args
permitted
oops! last line was supposed to be:
auto x = f(y); //function pointer call, so fewer args permitted
And for the record, 'argc' in the above is a name that has a
similar status to 'this' and is equal to the number of arguments
actually passed. Probably there's a better choice of name.
