How to execute same code for callback and errback?

[Christoph Pilka]

In one of my cases I have to execute exactly the same code within
callback as well as in errback. How would you avoid DRY in such
situation?

Some EM methods allows both a Proc instance of a block. In the former
case you can do:

my_proc = Proc.new do |param|
# do something with param
end

em_object.callback(my_proc)
em_object.errback(my_proc)
