Generic Parameter Type Assertion

Dynamic type assertion on generic parameter type is not possible at runtime, but there's a trick to do it by converting the value to any and do the normal type assertion. This means T.(type) is not possible, but any(T).(type) is possible:

func checkMe[T any](t T) {
	switch any(t).(type) {
	case []byte:
		println("[]byte")
	case string:
		println("string")
	default:
		println("other")
	}
}

Playground

Although this tricks work well, but it is considered as unsafe since checking type at runtime could be very error-prone.
