If a is an object that contains the isEqualTag, then this function
will call that method and return whatever that method returned. If b
contains the isEqualTag, it will attempt the same with b. This way,
you can define your own classes with custom equality operators. See the
isEqualTag for more information.
Built-in JavaScript objects are just checked as if they were encoded to a
JSON format and the resulting ouput is identical. For exmple, two plain
JavaScript are the same if their enumerable keys contain the same values.
