Ugh. Toggling internal state like that will leave you in mutex hell if
you're trying to write thread-safe code.

I suppose I wouldn't object to:

  class Hash
    def <<(kv)
      self[kv[0]] = kv[1]
      self
    end
  end

  h << [:language,:ruby] << [:creator,:matz] << [:users,:"comp.lang.ruby"]

but I've never felt the need.

Regards,

Brian.
