Hello again everybody,
Chelly question made me think to something. Suppose I have a list like this:

p={a b (c 3 d)+a c (b^2 5),b (c+d 4)-a,-(a^3 d) c}

in which the round parentheses (except for the middle one) are unnecessary
but play a semantic role by dividing some expressions from others with
different meaning. Now let's say I want to extract the expressions inside
those parentheses and obtain

ans={{c 3 d,b^2 5},c+d 4, a^3 d}

Is there a quick way to do that?

thanks
