Just a very small nit to pick ...

... or rather not even a nit, just something I'd like to share:

I nowadays try to format my code in a "diff-friendly" style. E.g., I add a final period and carriage return to the last statement in a method (unless it's a return). That way, you only get a simple "+" line when you add something at the end.

See, not really important, but hopefully worth sharing nonetheless ;)
