This PR introduces the parametric attribute
[grind]for annotating theorems and definitions. It also replaces[grind_eq]with[grind =]. For definitions,[grind]is equivalent to[grind =].The new attribute supports the following variants:
[grind =]: Uses the left-hand side of the theorem's conclusion as the pattern for E-matching.[grind =_]: Uses the right-hand side of the theorem's conclusion as the pattern for E-matching.[grind _=_]: Creates two patterns. One for the left-hand side and one for the right-hand side.[grind →]: Searches for (multi-)patterns in the theorem's antecedents, stopping once a usable multi-pattern is found.[grind ←]: Searches for (multi-)patterns in the theorem's conclusion, stopping once a usable multi-pattern is found.[grind]: Searches for (multi-)patterns in both the theorem's conclusion and antecedents. It starts with the conclusion and stops once a usable multi-pattern is found.The
grind_patterncommand remains available for cases where these attributes do not yield the desired result.
