I was reading with interest the blog post on Traversal-enabled objects (�http://www.humane-assessment.com/blog/traversal-enabled-pharo-objects�) when I noticed the method #deepCollect: referenced. �Interestingly, I have a method called #deepCollect: that is use (wtih related methods like #deepDo: and #deepSelect:). �I suspect these uses may be compatible, with the traveral versions being more generic.

My set of #deep methods allow arbitrary flattening of collections. �The #flatCollect: suite in Pharo today flattens objects 1 level; the #deepCollect: flattens the collections as many levels deep as they are nested. �I found this to be a really useful ability when I work with PetitParser parsings, which tend give back massively nested Arrays by default.
