I think this could be easier to implement than you may think. All what
you need is to create an instance of mcs compiler (keep it in memory)
and then use REPL interface to compile modified code using same mcs
instance. You will have to tweak our REPL to compile in correct context
but that should be almost all what needs to be changed.
The bad news is that mcs does work properly on Mono runtime only. But as
Miguel wrote I am working on a solution and it should be ready in next
few months. You can play with current mcs as the new version should only
make things easier for you, e.g. you could get compiled method body as
