I do not speak Scala, but I guess the methkd's return value will be its last
statement's value. For void methods this might not make much difference (no
idea), but generally I suggest you explicitly return the result of 'proceed()'
(or whatever you want to return instead) if 'proceed()' is not the method's
last statement.
