Python - Zero-Cost Exceptions

In previous releases of Python, even if it was successful, there was a little bit of overhead to set up the mechanisms of potentially handling the errors. This wasn't just the overhead. You defer more of that, right? Yeah. The important thing here is that just there was lots of runtime information we need to maintain and we don't now. So, that again, shrinks the frames and just makes calls faster because calls in Python were notoriously slow.
