There is helper code in Prelude.pm.

Moving primitives from Prim.hs to Prelude.pm has been a goal for some
time.  However, there are difficulties, some of which this file tests for.

 - our &*f ::= &g; doesn't actually create a global.
 - Global multis behave non-multi, disappearing upon another declaration.
