This PR adds a linter (`linter.unusedSimpArgs`) that complains when a simp argument (`simp [foo]`) is unused. It should do the right thing if the `simp` invocation is run multiple times, e.g. inside `all_goals`. It does not trigger when the `simp` call is inside a macro. The linter message contains a clickable hint to remove the simp argument. I chose to display a separate warning for each unused argument. This means that the user has to click multiple times to remove all of them (and wait for re-elaboration in between). But this just means multiple endorphine kicks, and the main benefit over a single warning that would have to span the whole argument list is that already the squigglies tell the users about unused arguments. This closes #4483. Making Init and Std clean wrt to this linter revealed close to 1000 unused simp args, a pleasant experience for anyone enjoying tidying things: #8905 |
