Problem 1: Stacks and Bags

Our goal is to make it so that we have a stack equality operator that is both a stand-in replacement for bag's equality operator and does the right thing when dealing with a stack operation. Liskov suggests that you could define something like Bag#bag_equal?, which Stack must expose and implement to match Bag's behavior, and that you could add a second stack_equal? method for doing ordered comparisons. However, this feels like a kludge to me, and so I tried to take another angle, following a pattern found in Ruby's Numeric class (i.e. its integer? and float? methods):

require "set"

class Bag  
  def ==(other)
    [Set.new(data), limit] == [Set.new(other.send(:data)), other.send(:limit)]

Browser API wishlist

Native event delegation

Browsers could do so much more to optimize delegated handlers at a lower level. Most of the CSS selector parsing and grouping optimizations could be applied here. No javascript code ever has to be invoked if the selector doesn't match.

document.addDelegatedEventListener("mouseover", ".tooltip", listener)

Possibly coming with Web Components.
