That's unrelated. You can point to another primitive just by recompiling methods. No need to recompile the VM. ;-)

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
It will allow us to switch primitive tables at run time without
recompiling the VM.
