Why not some more simple compromise such as allowing empty commas.
This way, all the default parameters don't have to be at the end
of the list.

int foo(a = 3, b, c = 12, d = 12);

	foo(4, 7, , 10);     // c gets 12
	foo(, 6);            // a gets 3, c gets 12, d gets 12
        foo(4,,7);           // **error**  b has no default

Or am I naive?
