What's the type hint for "can be converted to" mean?
<p>Let's say I want to accept anything I can call <code>int()</code> on, or anything I can call <code>str()</code> on. How do I do that with the new type hints ?</p>

<p>Annotating with <code>typing.SupportsInt</code> doesn't work, as mypy will warn against passing a string.</p>
