Should Symbols be observable? about observer-util HOT 3 CLOSED

I don't know how other people use this library and maybe that's something that's up to you (because this library is, after all, part of a bigger framework).

I for myself don't think that properties with symbols should be observed. In fact (and this is my point of view), the observable model should be a plain POCO. So, no symbols, not even Map/Set. Just simple JS primitives. After all, I usually observe a POCO object that the server gives me and after all the changes, I submit it back for updates (or a new one if I'm creating a new entry... not really a point here).

Of course I do use Map/Set/Symbols, but as you mentioned, usually to manage some internal state that should not be exposed and of course, not observed.

I think I will make symbol keyed and function valued properties non observable, because they do not express data (rather metadata and functionalities). Maps and Sets will stay observable though.

Edit: I might allow the users to fine tune it with a config in the future if there is need for it.

In the end functions and symbol keyed properties are not observable from version 3 (released today) and upward. Thx for you opinion, it helped me make the decision (: I am closing this issue
