Hi guys,

We are now able to author code on-line, which allows us to create a  
new class. We want to “insert” this new class into a module and make  
it “instantly” available to the using program(s) - without restarting  
them.

I think I remember reading that this is possible somehow, but I  
haven’t much of clue where to look on this one.

Thanks for any assistance on this!

Thunk

Look at the instance methods of Module, particularly include and extend.
