[issue37623] namedtuple integration for importlib.abc.Loader

[Andrew Yurisich]

You're right, I was invoking the namedtuple on the same line that I was
defining it, freezing it in the process.

I split it to into two statements, and snuck the __spec__ attribute between
the definition and the instantiation.

I'll update the examples on my GitHub issue in the morning, and probably
close the issue out unless I find something else that is blocking me.

Thanks for the input 👍
