Sounds like it would make sense to add a clippy lint for and(). Maybe open an issue? |

Copied from
or().Inspired by this StackOverflow question.
The PR for
or()mentions the Clippy lintor_fun_callwhich doesn't exist forand()(although there isunnecessary_lazy_evaluations). I still think this warning is also good forand(). Feel free to close if you disagree.
