I’d rather use something like “mutable accessor” for mutating fields:

```rust
let x = 6;
thing~value = x;

```

And for calling functions which takes `&mut self`:

```rust
thing
    ~mutate()
    ~mutate_again()
    .move_it();

```

If you interested, more use cases and syntax variations could be found in [this thread](https://internals.rust-lang.org/t/method-cascading-and-pipe-forward-operators-proposal/7384).
