Thanks. I understand that one way is to pass a reference to an object to 
My.

The second option of when needed wont work since My will call meth() at 
some point that i don't know. I would have liked to leave meth() blank 
so that callers can do what they want there.

Another approach I had is to pass a block in advance which is stored, 
meth calls that block.

However, i had sort of hoped somehow the reopened method could access 
scope of the class that was reopening it. You have clearly explained 
that it is operating in the space of the class itself. So no magic can 
happen here :(
