You could hack a diffing tool that reformats both the before and after and shows the diff of the generated text. This would not catch changes like --val x = [1] ++var x = [ ++ 1, ++]; as expected, while it would give you a slightly more verbose diff if the change was --val x = [short(), short()]; ++val x = [ ++ a_really_long_name_that_pushes_the_line_length(), ++ a_really_long_name_that_pushes_the_line_length(), ++];
