That's one way to solve my literal problem but I would really like to make ',' a higher precedence than '=' on that one rule (so it would shift instead of reducing 100% of the time).
Both sides should be rvals. What if someone wanted to do something like get_state().member[index].value, new_state, error_id = func(current_state, config) Is there no way to overload the way the rule resolves the shift/reduce? I tried prec and dprec several times one email is http://lists.gnu.org/archive/html/help-bison/2013-12/msg00022.html I tried using prec directly before and after the comma but that didn't override the reduce into a shift.
