I think the main problem we were trying to solve is making sure we can 
make future-proof dumps. So that would argue for allowing h0, v0, p0 
syntax in the reader, but not printing them out that way by default.

Also, if we don't already, allow hard regs to be specified by name in 
the reader, and maybe even require it for virtuals.
