Using `Optional[str]` instead of just `str` will let the editor help you detect errors where you could be assuming that a value is always a `str`, when it could actually be `None` too.

`Optional[Something]` is actually a shortcut for `Union[Something, None]`, they are equivalent.

on the <code>TEXT</code> instruction.
Otherwise, pointer information must be provided by
a Go prototype for the function in a Go source file,
even for assembly functions not called directly from Go.
(The prototype will also let <code>go</code> <code>vet</code> check the argument references.)
At the start of the function, the arguments are assumed
to be initialized but the results are assumed uninitialized.
