 Reporter:  SamB      |       Owner:              
     Type:  defect    |      Status:  new         
 Priority:  critical  |   Milestone:  0.7         
Component:  Grin      |     Version:  HEAD        
 Keywords:            |    Testcase:  UnpackedPoly
----------------------+-----------------------------------------------------
 For some reason, !UnpackedPoly happens to tickle some bug in Grin.FromE
 right now and cause it to generate Grin that references variables that are
 not in scope. At the very least, FromE is making some undocumented
 assumptions about the form of the E -- if so, they should be documented
 and checked.
