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
Joachim Breitner	e575736cae	feat: fun_induction to unfold function application in the goal (#8104 ) This PR makes `fun_induction` and `fun_cases` (try to) unfold the function application of interest in the goal. The old behavior can be enabled with `set_option tactic.fun_induction.unfolding false`. For `fun_cases` this does not work yet when the function’s result type depends on one of the arguments, see issue #8296.	2025-05-13 09:37:39 +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.)
