Subject: [boost] [Fusion] fold takes state by cref. Why ?

Why is the State passed by const reference ? I have a couple of use case
(like using fold to access the element (i0,...,in) of a fusion
sequence of pointer to ... pointer to T array) where I need to be able
to discriminate the constness of the State to forward to
the proper PFO overload of operator().
Is there any intrinsic stuff I am missing ?
