I agree. But should we have way to change the hash default initializer?

  class Hash
    def default=(&block)
      @default_initializer = block
    end
  end

(Except that I couldn't make the call succeed in any of these ways

  hash.default=   { "foo" }
  hash.default=() { "foo" }
  hash.default=   do "foo" end
  hash.default=() do "foo" end

but I guess my idea is clear anyway...)
