Yup. My mathematic intuition cannot suffer that:
4 < X < 2
to be true in any circumstances -- as it violates associativity.
If one wants to violate associativity, one should presumably *not*
use the chained comparison notation!
So Pugs will evaluate that to (#f|#f), by lifting all junctions
out of a multiway comparison, and treat the comparison itself as
a single variadic operator that is evaluated as a chain individually.
This way, both associativity and junctive dimensionality holds, so
I think it's the way to go. Please correct me if you see serious
flaws with this approach.
Thanks,
