The functions add_dependencies() and set_global() are convenience
methods that allow you to modify the global namespace while
the current file is running but then have it be cleaned up
by index.js when you're done.

This is like Python's dict.setdefault. I don't love the name, but
the consistency is nice.
We have lots of places where we do things like:
if (! dict.has('foo')) {
dict.set('foo', []);
}
var arr = dict.get('foo');
arr.push(3);
We can now write:
var arr = dict.setdefault('foo', []);
arr.push(3);

Dict.each() allows to iterate through values and keys of a Dict.
The callback function is passed value as the first parameter to
be similar to _.each()'s calling sequence.
