  Yep.
  
  I don't know why that hasn't been done.  That stuff dates right back
  to gmp 1, in various forms.  Maybe Torbjorn can remember the
  motivation.

Alas, no.

While I certainly agree that the current stuff is a gross hack,
I am inclined to let it stand.  It works, and editing it is more
likely to cause trouble than solve anything.
