Hi, I noticed that the cctbx azure pipelines run libtbx.find_clutter as part of the Python "syntax" jobs, and if they find any "clutter", then the pipeline immediately fails and doesn't run any further tests (e.g. https://dev.azure.com/cctbx/cctbx_project/_build/results?buildId=374). This raises the following questions: 1) Why skip running tests just because "clutter" has been found? 2) Why run libtbx.find_clutter as part of the "syntax" job, as strictly speaking trailing whitespaces, unused imports etc, aren't syntax issues? 3) If finding clutter is so important, why not add an optional pre-commit hook to help prevent "clutter" ever being committed in the first place?
