  Overhaul Lib/compiler block ordering.  The previous code was filled with
  hacks.  The new code is based on issue #2472 posted by Antoine Pitrou.  I

  need similar tweaks, I'm not brave enough to attempt it without being
  able to test.

  correctly (should be assigned using STORE_GLOBAL opcode).  This was done by
  having the system table differentiate between explict and implicit globals.
