If this is just for testing and you just want the info on the command line
then you could just go with something like

require 'pp'

and then inside the class add

def show_variables()
  pp @variables #This gives one blob of data
#or
  @variables.each{ |var| pp var } #This will break each variable onto a line
with [ key, value ] symantics
end

This will give you a "nice" output of what the data is inside the variable
list.
