The Odin Programming Language

Yes, the general idea is not new but the devil is in the details.

As far as I can tell, Odin's `using` is applicable in the same areas as Kotlin's, but I still favor Kotlin's scoped version. When I see "using foo;" in Odin, it's not quite obvious to me where the scope of applicability is.

Any reason why you didn't do something like

    entity.use {
      // "this" is now the entity instance
    }
    // back to your regular "this"

?

You can easily do the same in Odin, if you would like. However, `using` works for a lot more than that just this. `using` allows for many for type system features beyond a basic scope import like Pascal's with. `using` can be applied to procedure parameters, struct field declarations allow for subtype polymorphism (even of pointers), scope imports, and more.

Koltin's approach is limited to purely the same Pascal's `with` allowed.

But if you want to be clear:

    { using entity;
        // the fields of "entity" are not usable in this scope 
        x = 123;
    }
    entity.x = 123;
