What did you do?

define type:
type QuickSets[T any] []*QuickSet[T]

add func:
func (qs *QuickSets[T]) Clac(cmpf func(a, b T) int) (c []T) {
as1 := [][]T{}
for qi, a := range qs {
as1 = append(as1, qs[qi])
}
return c
}

What did you see happen?

cannot range over qs (variable of type *QuickSets[T])

What did you expect to see?

make it can range

[Jorropo]

Try *qs, you can't range nor index pointer to slices to begin with:

a := []int{42}
b := &a
for range b // does not work
b[0] = 1337 // does not work
