Because this feature is useful for other block based messages: people collect: #name >> #size people select: #name >> #size >> #even (I use >> as example). Generally it is about functional programming. Would be nice to have this in image because it will simplify scripting a lot. I remember nice set of blog posts from Vassili Bykov about such kind of things http://blog.3plus4.org/2007/03/.
