There were a couple times I wanted to expand a 1-bit signal into a 16-bit bus and came up with this one line, but rather inefficient, solution by thinking about strange ways to use the chips already made:

    Mux16(a=false, b=true, sel=1-bit-signal, out=16-bit-bus);

This is mostly just a cute trick, though.  It would be better to write a chip named something like Bus16 to do this job more efficiently.  It also makes the HDL more readable!
