Subject: Re: iterate through an array of method names to an object

But also the send method will expect to get a symbol not a string so
you'll need to do something like

functions.each do |funk|
    funk.to_sym
    puts name_o_my_object.send(funk)
  end

I tried that in irb and it worked so fingers crossed should work for
you too.
