Calling the proc stuff not mature might be totally fair when you consider that TFA got almost everything they wanted w/o it and the interface they got is more natural and the compiled code more efficient! Or it might just be fair to say that it is mature and just the wrong tool for TFA's task. I wouldn't know which is the case -- I'm not at the level of making my own categories.
