You have to remember that methods are just regular functions with the receiver as the first parameter. From the spec (https://go.dev/ref/spec#Method_declarations):
> A method is a function <https://go.dev/ref/spec#Function_declarations> with a receiver. This mean that if you detach the method from the receiver, which time.Time.Compare does, then it requires two arguments instead of one. a := time.Now() b := a.Add(1 * time.Hour) cmp := time.Time.Compare cmp(a) // error: not enough arguments in call to cmp cmp(a, b) // ok https://go.dev/play/p/x3ZGIhQ2TNE Diogo Lisboa On Thursday, February 20, 2025 at 2:57:35 PM UTC-3 cpu...@gmail.com wrote: > Sorry for not finding a better than this click bait subject. > > In https://github.com/golang/go/issues/62642 this suggestion was made: > > slices.SortFunc(times, time.Time.Compare) > > It's totally unclear to me how Time.Compare matches the compare func(a,b > T) int signature?
