With the private name proposal obj.foo and obj.[#.foo] will always mean the same thing regardless of whether foo is scoped as a private name or as a regular property name.  BTW, if you know that a property name is foo, why would you ever code obj["foo"] instead of obj.foo?  [ ]  should only be needed if the property name is not an identifier or is a computed value (hence my original example).
