Well, it is far from being "simply". Can you tell me what is $1 here? And what do you do in the following case?options: ( (opt1 | opt2) (',' (opt1 | opt2))* ) ? The question mark is part of the rule, not of my text body.
One will have to attach local actions within each rule, with their own $k values. Then use the hidden variables to expand into ordinary rules.
