More generally, a "new-style class" is important in this instance
because it inherits, directly or indirectly, from a built-in type,
becoming part of the main class hierarchy.

There are very few reasons to use old-style classes these days (and I
don't know what those reasons are anymore). Avoid them unless you know
you want them for some specific reason.
