On: Python adopts a 12-month release cycle

How's that different from just writing `async`, without `eval`?

i.e. if the string's static `eval` isn't doing anything?

The module would not be able to be imported due to the syntax error. Eval is required to make the module syntax correct.

That being said, don’t do this. Check the version explicitly.
