the sugar for what can be on the left side of an equals sign needs to

I'm not clear on why we need to reserve 'if', 'unless' and 'null' either,
since they never appear in locations that could be confused with variables.
there's not a strict reason, no. In fact, it
I checked in some major changes that allow all keywords (types and if, null,
etc.) as identifiers. Cleanup and maybe a refactor will follow later.

This is another one of those muddy cases in PIR where words conflict when
