This PR adds the new attributes
[grind =>]
and[grind <=]
for controlling pattern selection and minimizing the number of places where we have to use verbosegrind_pattern
command. It also fixes a bug in the new pattern selection procedure, and improves the automatic pattern selection for local lemmas.The tests
grind_constProp.lean
andno_grind_constProp.lean
are the same use case with and withoutgrind
.
