See PacmanTwo Bonus concern.
The Pacman.touch message is not send, this is because the Pawn class does not have superimposition and therefore the interpreter is not instrumented to process that message.
A dirty workaround to this issue is to superimpose a dummy filtermodule on the super classes so that calls to those methods are also intercepted by the interpreter.
