Re: [heycam/webidl] Sort out when dictionaries and records should have default values (#76)

> Is this the way it currently is, or what you're suggesting in OP?

This is the way it currently is.  To be clear,  in the current spec for function arguments, `undefined` and `null` are equivalent to each other (and mean "empty dictionary") while `{}` is a bit more complicated because it involved property gets but generally means "empty dictionary" if people haven't modified `Object.prototype`.

For other dictionaries, still in the current spec, `null` means empty dictionary while `{}` means you  start getting properties off it, etc.

This is why I wanted to double-check what your  actual suggestion is: it sounds like you want to treat `undefined` and `null` interchangeably to mean "not present", which is not how it works _anywhere_ in webidl.
