Alright, thank you! Just knowing that this is thought of, on a todo list and currently not completely inaccessible helps build confidence somewhat; I th= ink for me enough to try some of this in production code. With some luck you st= ill get through your todo list faster than I get to my next corresponding relea= se :)=
