Right now, there is no way to do this, and there seems to be little
possibility in C.
Templating can handle this smoothly, but we would have to convert to C++. We
are weighing the options.

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which
their experiments lead.
