This is why you need good examples. Generalization is all very well,
until your audience fails to grasp why the generalization is actually
useful.

Consider the “descriptor” concept in Python
<https://docs.python.org/3/reference/datamodel.html#implementing-descriptors>.
Can you appreciate, from that bare-bones description in §3.3.2.2 and
§3.3.2.3, how useful they are? I certainly didn’t.

But on further study, I discovered that descriptors are key to how the
whole class system works in Python. Every function is a descriptor.
And then you discover that builtin functions like “classmethod” and
“property” are just conveniences: you could write them yourself in
regular Python code if you wanted to, since they don’t rely on any
magic internal to the particular Python implementation.

A similar thing applies to metaclasses.
