generic type lamda params infer error

[visualfc]

The following program sample.gop triggers an unexpected result

utils.go

package main

func ListMap[T any](ar []T, fn func(v T) T) {
	for i, v := range ar {
		ar[i] = fn(v)
	}
}

sample.gop

num := [1,2,3,4,5]

ListMap[int](num, x => x * x) // build pass
ListMap(num, x => x)          // build error

println num

Expected result

build pass

Got

sample.gop:4:13: cannot use x => x (type func(x T) T) as type func(v int) int in argument to ListMap(num,x => x)
