This is very half-baked, but I'm capturing an idea I wrote in an empty buffer.
This provides a similar behavior to Rust's std::option::Option enum which encapsulates a value either existing as it should as "Some" value, or being empty or "None".
There's also a convenience for pattern matching, though more would need to go into the typing with PHPStan docstrings to make it more dynamic. As it is now though, it's possible to act on a Some or None match with a closure for the items.
In my specific scenario, I am using fish but installed by the Nix package manager on macOS.
The following configuration resides in my user settings JSON file.

This demostrates a scenario of generating persistence-layer agnostic domain models which reflect the context of your service, but are not explicitly tied to a data store (in this case, MongoDB)
The pattern enforces separation of concerns such that the persistence layer and domain layer are kept independent of each other.
One important component here is the interface, IUserRepository, which we could swap with any other implementation backed by whatever data store. You can swap in a Fake for e2e testing that is backed by an in-memory datastore.

Write a function:
function solution(A);that, given an array A of N integers, returns the smallest positive integer (greater than 0) that does not occur in A.
For example, given A = [1, 3, 6, 4, 1, 2], the function should return 5.
