what about having some Tree related trasnform/function/meta-function then ?

I'm often thinking : "dang, this transform is basically a BFS for a node 
verifying meta-function foo<>"
and have to rewrite a BFS usign default_ and such, which is relatively easy.

Now, sometimes it is "dang, this code is basically splitting an AST into 
multiples AST everytime I found a bar tag" or "I need to do a DFS"
or even worse, I need to make the AST a DAG :E ...

Do people think such stuff (maybe in proto::tree:: or smthg ?) be useful 
additions ?
