Ah, if you’re making dsl code or functional combinators, you usually want to ‘move’ your values instead of ‘borrowing’ them.

example:

fn add(mut self) -> Self { self }

fn add(self) -> Self { self }

instead of:

fn add(&mut self) {}

fn add(&self) {}

With this, you will be able to ‘store’ closures easily and apply them later. No more fighting with the borrow checker over where to borrow as mut or not. You will also avoid a few copies.
