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;
