  2. What is the meaning of the comment after the PrimTypes (re)declaration at
! the top of system/smlnj/init/built-in.sml?

! 3. The Single Generalization Conjecture: Each type metavariable that
! is not instantiated is generalized at a single variable binding.

! the corresponding generalized polymorphic variable.  [The code for mkPE
! in translate.sml seems to imply this is not the case.]
