Subject: manufacturing methods

Hi there.

Apologies if this is covered somewhere... all the googling I've done on the subject has wound up with info on class-factories and and using variables in methods.  Not exactly what I'm looking for.

The question I've got is related to manufacturing methods.  In my particular case, I'm using a module that relies heavily on callback methods.  I need to define a couple dozen callbacks which I'd like to all behave in basically the same way.  In order to keep my code simple, I thought I'd try manufacturing them all from the same basic code.. but haven't found a syntax that works.

Though this syntax clearly doesn't work, an example of the sort of thing I'm looking for might look like this, assuming I want to create the methods "on_foo", "on_bar", and "on_baz":

%w( foo bar baz ).each do |callback|
   def on_#{callback}
      # callback work here
   end
end

Is what I'm attempting to do even possible?

Thanks,
  Matt
