I once proposed exactly the same, with a --- token for a placeholder. Easy to read and to type.

myFunction( ---, ---, 10, ---, ---);

This stayed unheared. I think it doesn't make sense now, since this kind of addition can be made to 2.x D release, and the current semantics is out of question to be tampered with anyway.
