    Is there any reason an OO language couldn’t have a borrow checker? Sure, it would be wildly more complex to implement but I don’t see how it’s impossible.

      OO languages typically use garbage collector. The main purpose of the borrow checker is to resolve the ambiguity of who is responsible for deallocating the data.

      In GC languages, there’s usually no such ambiguity. The GC takes care of it.

      I would argue that rust has a very strong OO feature set (it just lacks inheritance which is the worst OO feature IMO). It is not seen as an OOP language as it also has a very strong functional and procedural feature set as well and does not favor one over the other letting you code in any style that best fits the problem you have.

      So I would not say OO and a borrow checker are impossible or even hard. What makes less sense is a GC and the borrow checker. Though there are some use cases for having a GC for a subset of a program.
