It seems to work here


bschroed@black $ cat send.rb
class A
  def send_it method_name
    send(method_name, "Send from #{self}")
  end
end

class B < A
  def select(msg)
    puts "Received: #{msg}"
  end
end

b = B.new
b.send_it(:select)
bschroed@black $ ruby send.rb
Received: Send from #<B:0x402a9b9c>
bschroed@black $ ruby -v
