Leonardo de Moura	52d4189805	feat(library/tactic): add dsimp_config configuration object for the dsimp tactic family ... Now, `dsimp` fails if the goal did not change. We can use the config object to obtain the previous behavior: ``` dsimp {fail_if_unchaged := ff} ``` See comment https://github.com/leanprover/lean/issues/1694#issuecomment-310956315 at issue #1694	2017-06-30 17:15:10 -07:00
