Well, that doesn't really work, as "StaticOptional[T]" can't be used as the type of a variable. It can only be used to create another generic function.

For example, this doesn't work [0]:

  //compilation error: interface contains type constraints
  func TryParse123(s string) StaticOptional[int] {
     if s == "123" {
       return StaticSome[int]{123}
     }
     return StaticNone{}
  }

My bad. I was not aware on incredibly limited go generics are. I tried to make it work despite all restrictions but gave up here https://go.dev/play/p/XVTuJ--ZLgS

I'm not well versed in golang generics (at $WORK we use go, but not generics yet) but if you want type switches you'll need interface{} to do that https://go.dev/play/p/1Tn2O_7vCTQ

Which of course defeats the point of using generics

_edit: clarify that my attempt is a bad practice_
