I have a question about define_method, more specifically how to bend
it to my purpose.

The problem I am trying to solve is I have an object "Action" which
basically carries out a static set of actions based off instance
variables. "Action" can also be modified by MANY "Modifier"s. A
"Modifier" just adds in a little bit of extra code that can changes an
"Action"s operations just a bit. (Example: Action with a Modifier to
email someone with a report, something I wouldn't want on every object
and don't want to lump into some sort if/else statement in Action)

What I would like to be able to do is have an empty method
"Action.runModifiedCode" within the "Action" class that would allow me
to just inject the code right into "Action." This is easy enough to do
using define_method (or a mix-in) to override the mock method, but
this doesn't work when the "Action" has more than one "Modifier."

Long winded story short, is there something that would allow me to
take the code from one object method and append to another object's
method?
