That shouldn't be necessary as it can easily be written in a single list
comprehension:
a = [[1,2,4],4,5,[2,3]]
flat_a = [x for cur, rest in [[a[:1], a[1:]]] for x in cur
if (not isinstance(x, (list, tuple))
and (not rest or not cur.append(rest.pop(0)))
or (x and (cur.append(x[0]) or rest.__setslice__(0, 0, x[1:])))
or (not x and rest and cur.append(rest.pop(0))))]
