Joachim Breitner	e7b61232c9	feat: more parameters in `.fun_cases` theorem (#8359 ) This PR improves the functional cases principles, by making a more educated guess which function parameters should be targets and which should remain parameters (or be dropped). This simplifies the principles, and increases the chance that `fun_cases` can unfold the function call. Fixes #8296 (at least for the common cases, I hope.)	2025-05-16 09:06:21 +00:00

feat: more parameters in .fun_cases theorem (#8359 )

This PR improves the functional cases principles, by making a more
educated guess which function parameters should be targets and which
should remain parameters (or be dropped). This simplifies the
principles, and increases the chance that `fun_cases` can unfold the
function call.

Fixes #8296 (at least for the common cases, I hope.)

This PR improves the generation of `.induct_unfolding` by rewriting
`match` statements more reliably, using the new “congruence equations”
introduced in #8284. Fixes #8195.
