I think it has nothing to do with extend method:
sage: def f(n):
: print(len(l))
:
sage: l =
[]
It is not fake. If your iterator uses a reference to
the underlying list, then the behavior is different
sage: l = []
sage: iterator = (len(l) for i in range(3))
sage: l.extend(iterator)
sage: print(l)
[0, 1, 2]
sage: l = []
sage: iterator = (len(l) for i in range(3))
sage: l[:] = iterator
sage:
So, my example is fake?
