Nice!
I agree that it is easy to use _PyType_Name() directly. But using
_PyType_FullName() instead of tp_name can be cumbersome because it returns a
new object and needs error handling.

Yes, I think we need a convenient way of formatting fully qualified name that
omits the module name for types in the builtins module. It is equivalent to
Py_TYPE(obj)->tp_name for extension types which is the most popular way to
format a type name in error messages for now.
There are several open issues for inconsistency in error messages for Python
and C implementations, because the former use type(obj).__name__ or
obj.__class__.__name__, and the latter use Py_TYPE(obj)->tp_name. I hope
finally we will fix this.
