I assume you want to document the new WeakMap class of the core, but this page is about PECL/weakref. I have no idea how to resolve that (search etc.)

Well carp. Yeah, I did. I figured this page was just auto-generated at some point and ran with it. How do we add a native version but avoid namespace collisions on IDs?

Frankly, I have no idea. That was one of the reasons why I suggested to rename WeakRef to WeakReference, but I couldn't come up with another name for WeakMap. :(

Proposal: Rename class.weakref to class.ext-weakref, then create a new class.weakref page back in the "built-in" section that documents the one in core. The extension is unlikely to get much if any use in the future now that the functionality is built in.

Thoughts? Yay/nay?

Not weakref but weakmap, though. :)

Right, that thing. 😄

Let's see if the bot likes this version.

(All of the new pages are copy-pasta from the extension, with the new description text. It looked like that was all accurate to me so I didn't bother changing anything.)

Rebased now that the old WeakMap class from the extension is gone. Bot appears happy.

The pages are not used yet; you need to add &language.predefined.weakmap; to language/predefined/interfaces.xml. Then CI will likely fail. :)

Furthermore, there should be respective entries for the class and its methods in language/predefined/versions.xml.

You need to list the entity references of the methods of Weakmap on its page, not the entity reference of the class itself:

So we're good to go. Thank you!
