@randall77 requested issue #53419 to be considered for backport to the next 1.18 minor release.

@gopherbot please open a backport issue for 1.18.

Change https://go.dev/cl/416155 mentions this issue: [release-branch.go1.18] cmd/compile: only check implicit dots for method call enabled by a type bound

[gopherbot]

Closed by merging 93aab18 to release-branch.go1.18.

I merged this CL accidentally, but the cherry-pick seems reasonable retroactively. Approved.
