There was a problem hiding this comment.
What about adding this block of code to call_intrinsic instead? It's about the same amount of work and wouldn't hide unstable feature usage like the previous implementation did.

Gah, sorry about the regression! It's not clear to me here what actually regressed, but the solution looks fine. |
|
@alexcrichton no worries. |
|
Ah I see, that'd explain the lack of regressions in the main repo! |
#35957 made old-style attribute syntax extensions no longer allow internal instability.
