If there were several proposals, we could review all of them together. We already did that for the thread/futures proposals. Ah, that's exactly the kind of thing I was looking for, thanks. So we've had previous experience with this. Great.
* do we want a Hana style with "concepts" and with customizations? Do we want other data type than type lists? IIUC Peter's library works only with template aliases as data types and almost variadic class template with type parameters is a good candidate for a type list (even std::variant :( ) As far as I can tell, none of the proposals have Hana-style customization points and concepts, but I see no reason to explicitly request that they provide them. I'm happy as long as there's some way to interoperating with other libraries. I'm not requesting that the meta libraries customize Hana concepts as Boost.Hana has values. I would like we discuss if we adapting those meta-concepts to the meta world could be useful or not.
However I see only one official proposal (mp11 - Peter Dimov), even if there are other interesting libraries (as Meta, Brigand). You're right. I thought Bruno Dutra's Metal had been officially submitted, but not yet. In any case, it's just a matter of days or weeks. Who knows ;-)
