Functional programming

• List handling (now available in dynamic languages)

• Partial application

  • map (round 0.01) [ 1.333, 4 ]

• Closure (now available in many languages)

  • b1 = Gtk::Button.new("One")
  • b2 = Gtk::Button.new("Two")
  • b1.signal_connect(clicked => sub {
    • b2.set_sensitive(0)
  • })
  • Without closures, b2 should passed as a parameter (via void* ?) or via a global/class variable
