That's one of the reasons I used a multi-pass design in tniASM :) It just
keeps processing the code until everything checks out. It might be slow,
but I don't have to remember anything and forward references take care of
themselves.
Ofcourse for an assembler running on MSX it would be totally unpractical
for speed reasons, I think...
Anyway, I don't think anyone would want a Z380 assembler run on Z80/R800.
Is Compass prepared for doing 32-bit math on expressions?
I think a Z380 assembler should be run on Z380. And if a proper C compiler
is made, a Z380 assembler can simply be ported to it.

JR16 and JR24 are better IMO.
