3 days left to pledge for Python in Light Table(kickstarter.com)

  1.  Globals (which includes classes) are trivial to detect and centrally stored,
      making it easy to pick up when a class is used in source code.  So we've
      now got autocomplete for all static methods and class documentation.
  2.  Most of the time, a variable is only actually assigned to once--or,
      worst case, from one location.  After that, it's merely manipulated.
      See what class is getting instantiated there (see above), and you've got
      a great guess on what type you're dealing with.  (And, sadly, it's a
      guess; "Foo new" *probably* gives you a new Foo, but it doesn't have to.)
  3.  Most methods *either* only get implemented once, *or* specialize a
      method whose parent calls "self subclassResponsibility".  So either
      you've only got a single place to look-up, or you can hedge your bets
      and show documentation for the version of the method that calls
      "self subclassResponsibility" (i.e., the abstract one) and figure it's 
      applicable to the concrete instance.
