Oh, I am sorry. I did not expect the linter to complain. |

what is the best way to do the split in git? I would just cut and paste all the nondegenerate stuff into a new PR, but maybe there is a better option |

…generacy (#12269) Several lemmas needed to define nondegenerate bilinear forms and show that the canonical pairing of the algebraic dual is nondegenerate. Add domain restriction of bilinear maps in the second component and in both compenents. Some type-class generalizations for symmetric, alternating, and reflexive sesquilinear forms.

… new file. (#18468) This cuts the import path. The copyright comes from #12269. I chose not to just move these lemmas to `linear_algebra/basis` as this file is already huge. The moved lemmas are now stated slightly more generally (`comm_semiring` rather than `comm_ring`), which seems to have been an accident in the original file as no proofs had to change.
