Are we still using WillBe types? I think they're all being removed right now.

[Marijn Kruisselbrink, 2016/03/31 19:01:48]

We definitely were still using them last week, and I don't think haraken has
managed to land any of the CLs that remove them yet even now. Of course if those
have landed before this is finished, there won't be a need for WillBe types here
anymore.

Got it. I thought those had landed; hadn't finished reading the entire threads.
