:-)  If we were starting from a clean slate, then yes, I'd agree.  But
starting from where we are now, I don't think it's worth changing what
already exists.

Note BTW that both current-module and current-reader are
Guile-specific.  For implementing something not Guile-specific, we
should also take into account portability of the chosen syntax; but
for these cases we don't need to.

(Sudden confusion: Are fluids part of R5RS?  If so, why do we need the
parameters SRFI?  I guess I need to go and reread it.)

Yes, but as ever there are other principles too, in this case back
compatibility and simplicity.
