Why should the parser treat primitive keywords differently from other
keywords? Why not let primitives also be handled like any other pragma
and have the handler return a flag to let the parser treat the pragma as
It just occurred to me (strawman alert!) that the parser could parse
<primitive: 'prim42' module: 'primitivePlugin'>
It will allow us to switch primitive tables at run time without
recompiling the VM.
