i.e. the idea of running RTL code from inside the C frontend seems to
be banned.
Yea, we really don't want the front-ends to know about the guts of RTL.
This work would seem to violate that guiding principle.
I'd be more in favor of a true RTL front-end rather than bolting it onto
the side of the C front-end.
