unique: panic when calling unique.Make with string casted as any [1.23 backport] #68992
Description
@mknyszek requested issue #68990 to be considered for backport to the next 1.23 minor release.
@gopherbot Please open a backport issue for Go 1.23.
This problem accidentally limits what types the
uniquepackage can work with, and results in panics. Also, the fix is very simple and low risk.
