That script should be deleted, it's absolute garbage.
Only a Sith deals in absolutes.
Is that a star-wars thingy?
In C 0 is a valid way to spell false, equally, any non-0 value is a
valid way to spell true. Why would this rate a warn?
In fact, when casting _Bool to integer, you get 0 and 1. When looking at
the memory content of the _Bool variable, you'll get 0 and 1. But we're
not allowed to write 0 and 1?
