In my opinion, that should evaluate to 1 < 1 // false because we have a post-increment operator, and it seems to me that the expansion defined for Python[1] makes most sense: > Comparisons can be chained arbitrarily, e.g., x < y <= z is > equivalent to x < y and y <= z, except that y is evaluated only once > (but in both cases z is not evaluated at all when x < y is found to > be false).
