You can stack wrapper methods in a class, so that

|   class Foo
|     def foo
|       print "foo"
|     end
|     def foo:wrap
|       print ":"; super; print ":"
|     end
|   end
|
|then, later reopen the class and:
|
|   class Foo
|     def foo:wrap
|       print "."; super; print "."
|     end
|   end
|
|...and expect that calling Foo.new.foo will print ".:foo:."

should work as you expected.  I haven't designed the API to remove the
around (and before/after) methods yet.
