This is better, and I believe it is even mentioned in the official
tutorial. A problem with this is that you don't get a lot of the nice
methods the dict class provides you with to iterate over its
keys/values, find keys, and more such things.

You *can* do it this way. But do you have a specific reason for *not*
using dicts? Because that would be the idiomatic way.
