to be honest i wasn't really thinking about the APE world.  i was
thinking about how programs in the plan 9/inferno world might find out
about particular classes of error that they care about.

this:

nonexistent(e: string): int
{
	errs := array[] of {"does not exist", "directory entry not found"};
	for (i := 0; i < len errs; i++){
		j := len errs[i];
		if (j <= len e && e[len e-j:] == errs[i])
			return 1;
	}
	return 0;
}

is not good enough.
