@findleyr requested issue #48819 to be considered for backport to the next 1.17 minor release.

@gopherbot please consider this for backport to 1.17, it's a regression.

@findleyr We've kicked this down the road for a while, does it still rate a cherrypick?

Ping. I plan to cut the minor releases tomorrow.

Sorry, thought I'd replied on this.

@griesemer would you be able to create a cherry-pick of CL 354349?

Update: I'm considering it, it's not set in stone yet. :) I'm trying to get a read on how many of these are very close to getting cherry picked. We already have a bunch of fixes that we should probably release soon.

FWIW I don't think our failure to land this cherry-pick should block a minor release, though I do still think we should fix this.

I'm on it.

@findleyr Good to know. I wasn't planning on blocking, but I did want to give a heads-up.

@mknyszek the cherry-pick CL is ready. It contains a additional fix related to generics that wasn't in the main-line CL (because it was otherwise avoided). Normally that would be concerning, but since that code change was on the _TypeParam type, which won't be produced when type-checking non-generic code, we feel that this cherry-pick is still safe. The effective change is one line, and well understood.

However, neither @griesemer nor I have permission to merge this cherry pick. Could someone on @golang/release do it?

Done! (I do have permission.)

Ah, GopherBot is currently rate-limited. I'll close this manually to help keep track.
