One point about this that came up at the face-to-face meeting:

  Putting properties on the global object is an important use case.
We don't want people to need to reach for |var| when they want to do
this (see t-shirt discussion).  Therefore, we may well need to
compromise some cleanups we might make to the top-level otherwise if
it wasn't for these two constraints.
