X := Eiffel
Y := Common Lisp

If wish that the :before :after method to patch a method would
be in Eiffel.

:before and :after let you define a function which is to be called
everytime before another is executed. after does the same thing
after the method is executed.

So you can do some kind of what is called  "multiple separation of
concerns".

For example add "semaphore.aquire" and "semaphore.release"
around a function without touching the source of the function.
