Gleam's `use` expression simplifies handling callback functions, error management, and context management. Introduced in version 0.25, `use` replaces the need for extensive nested callbacks, making code more readable, especially when dealing with functions like `result.map` and `result.try` for error handling. It serves as syntactic sugar for creating cleaner and more maintainable code, similar to Rust's `?` operator.
