I don't see why we shouldn't make self aliasable?

[retep998]

🐰 👍 + self

[Kimundi]

👍 including self - there is no reason to treat it special.

[Manishearth]

👍 self should be included too

[eddyb]

Definitely want this, have been trying to use as in groups so many times and every time the compiler reminded me it's not a feature yet.
self is no different than the other entries in a group, at the syntactical level, so there's no point to disallow renaming it.

[nrc]

I think we should do this, and now seems like a reasonable time to re-open the issue.

[seanmonstar]

Updated to include self as renameable.

[aturon]

I've definitely wanted this from time to time. 👍 from me.

[sgrif]

Definitely 👍, this seems like a reasonable inclusion, although I've never had need for the self aliasing.

[Manishearth]

I have a working (but unpolished) implementation here

(Needs grammar changes/tests and I should probably reorganize the ViewPath AST stuff too)

[nikomatsakis]

It's official! The lang subteam has decided to accept this RFC.
