So you are arguing in favor of approach #1, right? Then I would make “your” Map
a subtype of Object. typeof is currently best limited to primitives (and to
distinguishing them from objects), so introducing a new result would suggest
adding a new primitive. But I don’t think that is necessary: Once the semantics
of [] have been changed in accordance with approach #1 then you can just write
a library that provides Maps and other collections.
