Solve the following python programming problem given the following code:
def _hard_fuse(self) : 
    'Fuse consecutive loops over different iteration sets that do not
        present RAW, WAR or WAW dependencies. For examples, two loops like: ::

            par_loop(kernel_1, it_space_1,
                     dat_1_1(INC, ...),
                     dat_1_2(READ, ...),
                     ...)

            par_loop(kernel_2, it_space_2,
                     dat_2_1(INC, ...),
                     dat_2_2(READ, ...),
                     ...)

        where ``dat_1_1 == dat_2_1`` and, possibly (but not necessarily),
        ``it_space_1 != it_space_2``, can be hard fused. Note, in fact, that
        the presence of ``INC`` does not imply a real WAR dependency, because
        increments are associative.' 
    def has_raw_or_war(loop1, loop2) : 
        return ((loop2.reads & loop1.writes) or (loop2.writes & loop1.reads) or (loop1.incs & (loop2.writes - loop2.incs)) or (loop2.incs & (loop1.writes - loop1.incs))) 
def has_iai(loop1, loop2) : 
        return (loop1.incs & loop2.incs) 
def fuse(base_loop, loop_chain, fused) : 
        'Try to fuse one of the loops in ``loop_chain`` with ``base_loop``.' 
        for loop in loop_chain : 
            if has_raw_or_war (loop, base_loop) : 
                return 
if (loop.it_space == base_loop.it_space) : 
                warning ('Ignoring unexpected sequence of loops in loop fusion') 
                continue

                continue

            maps = list (set (flatten ([a.map for a in common_incs]))) 
            maps += [m.factors for m in maps if hasattr (m, 'factors')] 
            maps = list (flatten (maps)) 
            (set1, set2) = (base_loop.it_space.iterset, loop.it_space.iterset) 
            fused_map = [m for m in maps if ((set1 == m.iterset) and (set2 == m.toset))] 
            if fused_map : 
                fused.append ((base_loop, loop,...
