This has nothing to do with generics. It is a FAQ regarding the conversion
of a container type value. You cannot modify the type of the object in a
container in a called context. This has been true before generics was
introduced. Ignoring generics what do you think should happen if you call a
function that requires a `[]any` slice and pass it a `[]float64` slice?
Consider this pre-generic example:
package main
func do([]any) {
}
func main() {
var a []float64
do(a)
}
