I started looking at this again briefly today, and I actually think
that string manipulation of this sort is a mistake. String
manipulation is error-prone, and having an interface defined in terms
of strings makes it hard for a reader to see what sorts of input are
valid and invalid. (It's also often somewhat less efficient). So I
think it is a good idea to improve the interface while we're already
changing code in this area.
