What I meant was that self would be different at A and B:
# A
with bus do
# B
tell :turn_on
end
As self is the receiver of any implicit method calls, you have to change it
within the scope of the block or `.tell` won't get called on `bus`.
As Lee said, it's evil. It's not obvious to the reader that you've changed
self, and all sorts of weird things can happen (to somebody else) down the line.
