That's why you should read the spec and not guess a function's definition from one example.

Otherwise you'll end up thinking that almost everything is simply an alias for constant True or 0 or Error, by popping in 0 to any operator you check.

No. Imho, a good language designer will make it possible to learn the language incrementally without surprises. For example, a tutorial on a language should not start with "please read the spec first or you may encounter some awkward and counter-intuitive behavior in areas you thought you had already mastered".
