Not at all, it makes perfect sense. X == Y always tests whether the
argument X is equal to the object Y regardless of what X and Y are.

Except for the exceptions, that's why the statement is wrong.

But there are no exceptions.

Sec 2.2.3:
Objects of different types, *--->except<---* different numeric types
and different string types, never compare equal;

The exceptions you mean are not exceptions to "'X==Y' means 'X equals
Y'". They are exceptions to "'X equals Y' means 'X is mathematically the
same as Y'," but that is not how equality is actually defined.
