Script Hierarchy

[David Bovill]

Which makes me think that "pass" works according to a strict hierarchy. If
you "pass" a handler call it will nto find anything in any of the libraries
below it in the hierarchy.

While on the other hand a straight "call" to the handler from a script
behave completely differently in that it will be picked up by any of the
libraries regardless of whether the calling handler was "above" the found
handler in the hierarchy.
