The idea is to let everyone's compiler verifies this patch, and also to avoid
possible bugs introduced in backporting/rebasing/merging - for example if a
patch in another tree addes one more implementation that uses the old order, we
can notice.
If you don't like this, we can be careful and don't move opaque; or after a
short while, move opaque back in a separate commit (since Markus already sent a
pull request).
