You can get rid of the duplication by doing a super-object containing the
functions, then cloning this object for all your "real objects". So no, that
wasn't the case. The reason was laziness ;-)
1: I needed to encapsulate the two different lists into something, and I chose
an object. Could've used a list with the two lists as the only elements, but
I just didn't.
2: When I tested my code, I just wanted to be able to 'do the source file and
then directly use the functions on my existing object. If I had put the
functions inside the object, then i would have to create a new object in
order to use the new functions. This is the laziness part.
So, there wasn't any clever reason. And anyway, I just wrote it to show how to
do the thing relatively elegant by separating the keys and the values into
two separate lists, instead of the approach everybody else uses by cramming
everything into a single list.
Anyway, it can be done a lot nicer than I have done.
