practical to autoload libraries like this?

lol i got a little drunk just from reading his reply

@wired not only that, it would exit with an error if the variable you tried to access wasn't a valid library. This just means you have to define all your class variables, which one should do anyway imo. Also i'd limit it to the Controller scope where i think most runtime library loading is done.

it just seems that the lazy loading of classes is one of the better ways to improve performance.
