It won't look up the *name* ‘bool’, but it will use that object. Any
boolean expression is going to be calling the built-in ‘bool’ type
constructor.
So the answer to the OP's question is no: the function isn't equivalent
to the type, because the OP's ‘bool_equivalent’ function necessarily
uses the built-in ‘bool’ type, while the reverse is not true.
