It's not in the strawman. It appears in the latest draft, though weirdly
enough Map.prototype.size is a function with an unused argument.
What about making it an getter instead of a function? I guess we also don't
need the extra parens to request for Map#keys, Map#values, Map#items.
For keys, values and items I think they are cleaner as methods since
+1
they return a new iterator every time.
If they were properties, I would expect the following to always be true:
map.items === map.items
