Typical to Go verbose style, but even that is better than nothing (example from the doc) s := []int{1, 2, 3} floats := slices.Map(s, func(i int) float6

Typical to Go verbose style, but even that is better than nothing (example from the doc) s := []int{1, 2, 3} floats := slices.Map(s, func(i int) float64 { return float64(i) }) Type inference for generic function arguments This is a feature we are not suggesting now, but could consider for later versions of the language.
