Variadic generic arguments in Go

Let's say I want to make the equivalent of the JavaScript `Array.splice` function in Go, for Slices. I have the following code: ``` func splice(slice []int, index, amount int, elements ...int) []int { newslice := make([]int, 0) for i := 0; i < index; i++ { newslice = append(newslice, slice[i]) } for i := index + amount; i < len(slice); i++ { newslice = append(newslice, slice[i]) } for _, el := range elements { newslice = append(newslice, el) } return newslice } ``` This example will work, but only for arguments of type `int`. I want to make it generic, and I know that I should give the variadic argument `elements` the type `interface{}`, but how do I create a new slice with the type of that interface from inside the function? In other words, how can I specify the type of the slice dynamically depending on the type of the arguments in the first line of the function, where `newslice` is created?
