Is there a way to expand copper without using expensive gates?

At one point I wanted to name some individual wires of a bus to make some code clearer so I wrote the equivalent of your Dummy as

    Chip Alias {
    ...
    And (a=in, b=true, out=out);
    }

Realize that since this is all simulation, it doesn't matter that there are "gates" hidden in Alias or your Expand16.

I put Alias.hdl in tools/builtInChips and it's available anywhere, just like the other built-in chips.
