feat: Refactor hint system Hints are now accessible using the CLI subcommand `rustlings hint <exercise name`. BREAKING CHANGE: This fundamentally changes the way people interact with exercises. 2019-11-11 16:51:38 +01:00			// Make me compile! Execute `rustlings hint functions5` for hints :)
Just remembered another function one I wanted to do 2015-09-18 20:28:27 -04:00
feat: improve `watch` execution mode The `watch` command now requires user action to move to the next exercise. BREAKING CHANGE: this changes the behavior of `watch`. 2019-11-11 13:38:24 +01:00			`// I AM NOT DONE`
