Imperative_state.Make
Functor building an implementation of IMPERATIVE_STATE
for a given type of states.

traverse_list state f [x1; x2; ...; xn]
is [y1; y2; ...; yn]
where yi = f state xi
, and y1
, y2

are computed in order, meaning that y1
is computed first, then y2
, etc.
iter_list state f [x1; x2; ...; xn]
is f state x1; f state x2; ...; f state xn
.
traverse_reverse_list state f [x1; x2; ...; xn]
is [y1; y2; ...; yn]
where yi = f state xi
, and y1
, y2

are computed in reverse order, meaning that yn
is computed first, then y(n-1)
, etc.
