We don't have [].push(), and I don't think the metaphor really works
well with dictionaries. There's also an implied ordering relationship
between push() and pop(), and this doesn't hold for dictionaries
either.

There's only a limited amount on conceptual polymorphism between the
two; artificial extending that may lead to a lot of programmers using
the wrong structure for their application.
