I came up with an interesting use for [metaclasses], to allow
convenient definition of a hierarchy of exception classes representing
return codes from a given API. More details in the “Uses For
Metaclasses” notebook in this collection

Interesting. It is not clear to me why you need metaclasses to implement
the example, though.

On another note, C++20 introduces the concept of "concepts", which put
constraints on templates and their parameters.

In Python, that would just be another instance of the same type-annotation

language” versus a “run-time language”.

In other words, it is C++ that is struggling to keep up, not Python.

Whatever, dude.  Keep checking boxes in the feechure matrix.
