Kim Morrison	db354d2cde	chore: run Batteries linter on Lean (#6364) ... This PR makes fixes suggested by the Batteries environment linters, particularly `simpNF`, and `unusedHavesSuffices`.	2024-12-13 01:28:53 +00:00
Kim Morrison	a826de8a3d	chore: remove duplicated ForIn instances (#5892) ... I'd previously added an instance from `ForIn'` to `ForIn`, but this then caused some non-defeq duplication. It seems fine to just remove the concrete `ForIn` instances in cases where the `ForIn'` instance exists too. We can even remove a number of type-specific lemmas in favour of the general ones.	2024-10-31 07:40:09 +00:00
