Hi chris

I think that it would be great if:
	- your api is compatible with the one of doru
	- that we can introduce your extension to Pharo 
	- keep the package of doru outside because it is larger.

With such approach we could get a first version with your code and a larger one with the one of doru and people 
would love it on demand.

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.
