false is because dict() is a dict instance, not the dict type.

type({}) == dict == type(dict()) will always* be true.

This is part of the language spec, it is not something that can be
chosen by each interpreter.

*well, assuming that "type" and "dict" have not been reassigned from
their built-in definitions.
