Rather than inventing something more complex, I'm inclined to say we
should just go ahead and apply this more or less as Pavel wrote it. I
haven't tried to reproduce Pavel's results, but I assume that they are
accurate and that's a pretty big savings for a pretty trivial amount
of code. If it gets thrown away later when/if someone codes up a
precompiler, no harm done.
