Jeremy raises an excellent point. I wish I had read this post a few days 
ago. A few weeks ago, someone asked the question (paraphrased) "why do 
people use 'self.some_method' instead of just 'some_method'?".

I knew that I had a lot of redundant 'self's and a few days ago I got 
around to removing them in a script. As Jeremy points out, leaving off 
'self' in 'some_method=' results in the creation of the variable 
'some_method', as testing showed.
