OMG where did I see that? I'm drunk!

I am picturing a binary tree in my head...
Convention: left-side CBs are of the same levels, right side are
children. Let's say we have the following callbacks with dependencies:
A, B, C do not depend on any other callback
D, E depend on B
F, G depend on D
I depends on F

            A
           /
         B
         / \
       C  D
           /  \
          E   F
               / \
             G   I

The calling code will go first on the right side of the tree and then
left. This could be a solution, but it could have problems. Also the
tree will more than likely be unbalanced, but it will also be small...

Yeah even better... OMG I'm just dumb!!
