Topic: rule/assumption that do not unify schematic variables

Is there an equivalent to apply assumption and apply (rule ...) that do not unify schematic variables? I know in ML there exist eq_assume_tac and match_tac but is there an isabelle equivalent? Currently I use apply (tactic ...) as a workaround

Is the AFP an option for you or are you looking for something in the standard distribution?

rather the latter, i mean the workaround does work

Then there's no alternative as far as I know. In the AFP, there are assumption and rule methods with adjustable unification algortihms:
