The POE::Kernel documentation indicates this for call():
call() returns the value returned by the EVENT_NAME handler. It can do this because the handler is invoked before call() returns. call() can therefore be used as an accessor, although there are better ways to accomplish simple accessor behavior.
What are some of those ways? I tried a simple subroutine but don't seem to have access to things like the heap. I guess I could pass those in but than things don't seem as simple anymore.
