I think we should try. Similar idea appeared to me when I looked
at resuls of comparisons:
(7) -> 2 = 3
(7) 2= 3
Type: Equation(PositiveInteger)
It makes sense to try to "simplify" them to Boolean values if
possible. However, such step should run only when interpreter
has results from algebra or user function and is going to
present it (in program code types should decide what is
needed).
However, only experiments can show if such facility is useful...
