MyList is a list -- just a more specific kind of list -- as can be seen
from its mro; this is analogous to a square (2 sets of parallel lines

Possibly the worst analogy ever! *wink*

Also known as the square-rectangle problem.
A better analogy might be, Lassie is a dog, and Flipper is a dolphin, so
they are different types of animal. But both dogs and dolphins are
mammals, so in that sense, Lassie and Flipper are both mammals and
therefore the same type of animal. It depends on what you mean by "type".
I thought about using the mammal analogy instead, but geometry seemed
simpler. *sigh* Oh, well, can't win 'em all!
