The induction principle used by `induction` may have explicit parameters that are not motive, target or “real” alternatives (that have the `motive` as conclusion), e.g. restrictions on the `motive` or other parameters. Previously, `induction` would treat them as normal alternatives, and try to re-introduce the automatically reverted hypotheses. But this only works when the `motive` is actually the conclusion in the type of that alternative. We now pay attention to that, thread that information through, and only revert when needed. Fixes #3212. |
