Stack setup code is there mostly for completeness sake (that is, it allows starting from any node within any root). In normal use the stack build as you traverse.

Not sure what you mean. In general case there is no way to know if there is a trip to shadow tree between a node and its ancestor without walking the parent chain.

For future use. I plan to add some tests that dump the composed tree.
