Lots of bool operations shouldn't compile

According to the specification, booleans are a numeric type. true == 1 
and false == 0. So this error is not specific to bool.

Try s/true/1/g and s/false/0/g and you will get the same results.

The first two comparisons should be false I guess since they are 
unordered. The other two are correct.

(If it is wise to have bool as a numeric type is a different question.)
