Rewriting the construct in the front end, before noder, means the functions generated during
the rewrite are available in a noder-generated representation for inlining by the back end.

# Theory of Operation

The basic idea is to rewrite

	for x := range f {
		...
	}

into

	f(func(x T) bool {
		...
	})

But it's not usually that easy.

	// Similarly, using the poller doesn't make sense for pwrite.
	if err := fd.incref(); err != nil {
		return 0, err
	}
	defer fd.decref()

  // For the read-only case we only need that the last unknown write is already
  // tracked by the last `resource` write since we don't have dependencies to
  // any other read accesses.
  // Otherwise, we need that the last unknown read(s) and write are already
  // tracked by any read or write accesses of `resource`.
