I was trying to integrate your summarize closure implementation from mister-jones but belatedly realized it also breaks Options (at least as I've done it). Previously, the optionMixin was responsible for invoking subsequent summarization_op's so that missing values were removed.
I'm pretty new to Meta classes though so it's been a fair bit of stumbling around. Not sure if this has any useful code in it except the skeleton of a uniqueMixin.
