 owner                              | ☑   | an alias for a raw pointer
 not_null                           | ☑   | restricts a pointer / smart pointer to hold non-null values
 strict_not_null                    | ☑   | a stricter version of `not_null` with explicit constructors
-span                               | ☑   | a view over a contiguous sequence of memory. Based on the standardized verison of `std::span`, however `gsl::span` enforces bounds checking.
