like pass, but without ending the handler

[Chipp Walters]

Thanks Mark,

My issue though isn't with Python, but rather how to create an slick
interface callback system for Rev.

The idea being I would really like to be able to implement in my
library, in process function calls such as:

put getThisThing() into t1
put nowGetAnotherThing() into t2

without the developer having to implement a messy callback structure.
Not sure if this is even possible.

(Or if anyone else could describe a different type of way for handling
callback 'in process'?)
