Wouldn't this be equivalent to Any type?

I had to do some gymnastics to get a default sentinel type checkable in the BQ library:

I'm not sure. I do know that gapic_v1.method.DEFAULT_RETRY is just an instance of object.

Right. That's what I mean. object is a very generic type. Basically everything is object, so union with that is basically Any.
Would folks be open to making a more explicit type for the default sentinel like we did in BQ?

To test if it is equivalent to Any, we could try passing a string as a retry argument. It ideally should fail type checks.

I believe DEFAULT_RETRY is a specific object used as a canary.

If we update api-core to provide a different type for the marker object, then we can tweak the templates to use it -- otherwise, the typechecker hates that we are using that specific object as the default when we say the parameter is a retries.Retry.

Okay. Well I suspect this makes the type checker happy with any object, which isn't what we want. Did you see the pattern I used in google-cloud-bigquery? That pattern uses the fact that enums can be type checked to look for a specific object.
