I'm trying to think of what the output of this program should be: eval(1 = 2 = 3 / 0)
Since it should be equal to eval((1 = 2) = (3 / 0)) I'd assume it should warn as follows: m4:stdin:1: Warning: recommend ==, not =, for equality operator m4:stdin:1: divide by zero in eval: 1 = 2 = 3 / 0 m4:stdin:1: Warning: recommend ==, not =, for equality operator which would be the breadth-first left-to-right evaluation strategy, but instead it warns like so: m4:stdin:1: Warning: recommend ==, not =, for equality operator m4:stdin:1: Warning: recommend ==, not =, for equality operator m4:stdin:1: divide by zero in eval: 1 = 2 = 3 / 0 which is the depth-first left-to-right evaluation. Although, I'm not entirely sure. Regards, Nikolaos Chatzikonstantinou
