So, I was able to modify _1 (type of struct ptnode) by using a functor() (e.g. [_val = func(x, _1)] where the function will take a reference of _1 and do some modification to it and return (typeof(_1)&).
Can we also modify _val placeholder on the fly through semantic action? i.e. once _val = _1 executed, then modify the _val object
sure, i.e. arule[ _val=..., phx::bind(&someFunc, _val, ...)] No problem at all.
