+_Opzione_ (Italian "option") is a Go library for optionals, with tracking of nested pointers. You can add it to your project using `go get`:

 The package provides two basic optional types (containers), `Simple` and `Chained`.

 For value types, `Chained` is expected to behave the same as `Simple`.
