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.

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.
