That's sure, and I'm in fact glad to know that by now. I still think it's
risky, BTW. Python is dynamically typed, after all, and there's no 'a
priori' way to know if 'a' is a list or another type, especially another
If we rely on duck typing, by the way, we may encounter two types quacking
like ducks, flying like ducks, but in fact acting as slightly different
ducks. I should remember as well, when designing a container type that I
want to use in place of a list, to carefully craft an __iadd__ method which
works just like the a list's own __iadd__ method; if I forget, I may
introduce a subtle error.
