The documentation page: "Annotations - Decorating the ASTs" makes use of the 
"position_tagged" base class for an ast. It claims to provide the positions 
into the input (with iterators) that corresponds to a given element in the 
AST.

Maybe this does what I want. But I don't feel a need for an on_success 
function.

I'm going to write a fresh message asking about this position_tagged and if 
I can use it without that concept of annotation which I still fail to 
understand what that means.
