246In addition to specifying a boolean, you can specify a code reference that
247is called for every code execution attempt - the execution request is
248granted iff the callback returns a true value.
249
250Most of the time the callback should look only at
251C<$AnyEvent::MP::Kernel::SRCNODE> to make a decision, and not at the
252actual message (which can be about anything, and is mostly provided for
253diagnostic purposes).
