If `e` has type `T`,\nand `T'` is definitionally equal to `T`, then `@id T' e` typechecks, and lean\nknows that this expression has type `T'` rather than `T`. This can make a\ndifference for typeclass inference, since `T` and `T'` may have different\ntypeclass instances on them. `show T' from e` is sugar for an `@id T' e`\nexpression.\n",

"```lean\nId Nat\n```\n***\nYou can use parentheses for\n- Grouping expressions, e.g., `a * (b + c)`.\n- Creating tuples, e.g., `(a, b, c)` is notation for `Prod.mk a (Prod.mk b c)`.\n- Performing type ascription, e.g., `(0 : Int)` instructs Lean to process `0` as a value of type `Int`.\n- Creating `Unit.unit`, `()` is just a shorthand for `Unit.unit`.\n- Creating simple functions when combined with `·`. Here are some examples:\n - `(· + 1)` is shorthand for `fun x => x + 1`\n - `(· + ·)` is shorthand for `fun x y => x + y`\n - `(f · a b)` is shorthand for `fun x => f x a b`\n - `(h (· + 1) ·)` is shorthand for `fun x => h (fun y => y + 1) x`\n",
