Very quickly before I turn in for the night ... this goes a long way to making it clearer. Thanks. I'm going to take my own crack at this problem and see if I end up in the same place you did. Then we can compare/contrast. Oh, and I think you're right about proto::make_expr. It cannot make nullary expressions with tag types other than tag::terminal.
