I haven't looked at the implementation, but my understanding was that 1/3r was seen as 1 divided by Rational(3,1).  With that interpretation, I think 0.4/1.2r is not confusing: 0.4/1.2r is a Float (i.e. 0.4) divided by a Rational (i.e. Rational(12,10) or 1.2r).  Float divided by Rational gives Float.  To end up with a Rational result, use 0.4r/1.2r.

I very much like the idea of "1.2r", let's please keep accepting 1.2r.

Thanks,
Dave
