Why not try the design of Feel language,
There is no ambiguity and no more code.
```
type [Item T] struct {
Value T
}
func (it [Item T]) Print() {
println(it.Value)
}
func [TestGenerics T V]() {
var a = [Item T]{}
a.Print()
var b = [Item V]{}
b.Print()
}
func main() {
[TestGenerics int string]()
}
```
