Subject: More on psuedo arrays; Better way?

Newbie here:

Consider:



N_X_METHODS = 20

class X
  20.times do |i|
    define_method "x%02d=" % i do |arg|
      # the puts, below, is just a placeholder for a more complicated method
      puts "Hi " + i.to_s + arg.to_s
    end
  end
end


m = Array.new(N_X_METHODS) do |i|
  ("x%02d=" % i).to_sym
end

p m


10.times do |i|
  x = X.new
  
  # select a random method
  x.method(m[rand(i % N_X_METHODS)]).call(i)
end






Let's focus on the line
        x.method(m[rand(i % N_X_METHODS)]).call(i)


Is there a better way to do this?  Is there a more Ruby-ish way to do
anything else in the code, above?
