I'd have a Symbol.mode similar to Lua's __mode meta(method/field?) that would show the garbage collector that keys or values are weakly referenced in an object. Or even: obj[Symbol.weakValues] = true; obj[Symbol.weakProperties] = true; WeakMap isn't really all that special. Set is important for how it maintains only unique values are inserted - but you could do this with Proxy. I think I come across as a Lua fanboy... I enjoyed the minimalism of Lua for sure :-) I wish I could have weak references in arrays... :3 Iterate to .length, skipping undefined/null values (where things have been collected).
