No, Go generics do not exist at runtime, so there is no way for this to
possibly work in generality.
The best you can do is make a function that takes an `any` or a
`reflect.Value` and use `reflect` to type-check at runtime, returning an
error if type-checking fails: https://go.dev/play/p/c0jgBMxGd

Thanks for that solution. I guess I could do
t.Funcs(template
You can easily get it to work, but not in a useful way I guess.

You could have a different template for each type you use I guess.

Hi. I have a generic function
func slicerG[A any](s []A, i int) []A {
fmt.Println(len(s), i)
if i > len(s) {
return s
}
return s[0:i]

When I try to register this in a template's FuncMap, it fails with
"cannot use generic function slicerG with
