The top-level handlers list is just that, a list. The position in the list
controls the priority of a match. You can remove handlers by calling
'handlers.remove()'...

You could make a new kind of top-level handler that implemented your behavior -
so for example, your 'match' method would search its own list/dict/whatever for
matches under that portion of the tree. Hmm... a dictionary would probably
work pretty well. Then your top-level handler could be installed in a
'subdirectory', or perhaps as a default/fallback handler that you would install
at the end of the list.
