Here is anidea to kick around:

Evolve and eventually replace dict.setdefault with a more specialized method that is clearer, cleaner, easier to use, and faster. d.addlist(k, v) would work like d.setdefault(k, []).append(v)

-1: I use .setdefault all the time with non-list default arguments.

The dict interface is getting complex enough that adding more clutter will make it even harder to teach optimal idiomatic Python to newbies.
