Hi, these are just some spelling corrections.
There is one I wasn't completely sure about in
src/Init/Data/List/Lemmas.lean:

about \`List.mapM\` and \`List.forM\`
This PR tries to improve the E-matching pattern inference for `grind`.
That said, we still need better tools for annotating and maintaining
`grind` annotations in libraries.
closes#9125
This PR adds a verification of `Array.qsort` properties, trying to use
`grind` and `fun_induction` where possible.
Currently this is in the `tests/` folder, but once `grind` is ready for
production use we will move it out into the library.
Note that the current `qsort` algorithm has quadratic behaviour on
constant lists, and needs to be adjusted. We'll only move the
verification out into the library once this has been fixed (and the
proofs adapted). These verification theorems may be commented out in the
meantime if it's urgent to fix `qsort`.
