I wouldn't necessarily consider this abuse. This behavior (where
square-bracket- and dot-syntax are functionally equivalent) is the normal
behavior of JavaScript, and it makes dynamic lookup of method names a snap.
Python is more flexible in giving you the option to have separate namespaces
for items and attributes, but if it makes more sense for an object to merge
the two, I see nothing wrong with it.
