Function pointers/delegates default args were stealth removed?

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.
