In that case, would it be easier to understand(beside the original iterative loop) if I use reduce and lambda ?
reduce(lambda (mv,mx), (v,x): mv > v and (mv,mx) or (v,x), ((f(x), x) for x in mylist))) As while DSU is a very smart way to guard the max compare thing, it is still being introduced as a way that is not related to the original problem, i.e. I just want to compare f(x) -- http://mail.python.org/mailman/listinfo/python-list
