My feelings exactly. If you are going to go through the work, you 
should make sure that "the juice is worth the squeeze", so to speak. 
I rarely bump into an error where I stuff the wrong object into a 
collection, and if I do, it takes about 5 seconds to track it down. 
Don't you want to spend your effort on features that will have a 
larger effect on the time you spend coding, or significantly improve 
the quality of your program?
