Got curious after seeing something on reddit/r/ruby

Blocks vs modules

require 'benchmark'

module RoflModule
  def rofladd(ping, pong)
    ping + pong
  end
end

RoflBlock = <<BLOCK
  def rofladd(ping, pong)
    ping + pong
  end
BLOCK
class Modulefer
  include RoflModule
end

class Blockefer
  class_eval RoflBlock
end

puts "With Module"
puts Benchmark.measure { 1000000.times { Modulefer.new.rofladd(60,9) } }
puts "With Block"
puts Benchmark.measure { 1000000.times { Blockefer.new.rofladd(60,9) } }



Result:


rvm is a function
