Twisted (or for loops ?) madness

This is a well known issue of for loops. Some believe it to be a bug
but Guido says it
is a design decision, in the sense that Python always do late binding.
If you
browse this list you will find many discussions. Basically if you do

funclist = []
for i in 1,2,3:
  def f():
     print i
  funclist.append(f)

you will get funclist[0]() == funclist[1]() == funclist[2]() == 3 (you
get the latest
binding of "i"). As you see, it has nothing to do with lambdas.
