This PR adds the ability to register theorems with the `cbv_eval` attribute in the reverse direction using the `←` modifier, mirroring the existing `simp` attribute behavior. When `@[cbv_eval ←]` is used, the equation `lhs = rhs` is inverted to `rhs = lhs`, allowing `cbv` to rewrite occurrences of `rhs` to `lhs`. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> |
