//@ a *pointer* to such a type (be it a `Box` or a borrow) will need to complete this information. We say that pointers to

//@ table of function pointers, determining the code that's run when a trait method is called. There are some restrictions for traits to be usable

//@ In case of the `FnMut` trait, there's only a single action to be performed: Calling the closure. You can thus think of a pointer to `FnMut` as
//@ a pointer to the code, and a pointer to the environment. This is how Rust recovers the typical encoding of closures as a special case of a more
//@ general concept.

// same `t: T`, you will either have to restrict `T` to `Copy` types, or pass a borrow.
