My work currently is integrating with various shipping provider APIs
such as DHL. I have to deal with the enormous API request (and
response) definitions. I am just creating a DTO class for each level
of JSON key, which results in a HUGE amount of classes.

I have a hunch this problem can be solved better with anonymous
classes, but their support is not great yet - PHPStorm has a breaking
bug with their autocompletion and I am too dumb to figure out a better
solution in any case.

However, I totally agree with Levi in that the way forward is better
towards `new class() extends $someClass` and not "all anonymous
classes final by default". It may open patterns and opportunities we
have yet to think about.
