It seems we can potentially future-proof against new cases:

  > var options = document.createElement('select').options;
  > options.toString()
  [object HTMLOptionsCollection]

  > options instanceof HTMLCollection
  true

This could be used rather then individually checking class types.  But do you
think there will be a case where we wouldn't want to do a basic pretty-print an
HTMLCollection derivative? For instance indicating the "extra stuff".

  HTMLPropertyCollection has a "names" attribute
  HTMLOptionsCollection has add/remove functions

And DOMTokenList for the elem.classList has some neat functionality:

  https://developer.mozilla.org/en/DOM/DOMTokenList

My vote is that we should do a basic pretty-printing of not just HTMLCollection
but also its derivates. If people really want to know whats up they can do a
console.dir(...) on the object, but otherwise they should know what they are
dealing with and would welcome the pretty printing.
