AFAICT, the python iterator concept only supports readable iterators, not write.
Is this true?
for example:
for e in sequence:
do something that reads e
e = blah # will do nothing
I believe this is not a limitation on the for loop, but a limitation on the
python iterator concept. Is this correct?
No. e = blah will rebind the indentifier 'e' with 'blah' whatever that
is. That is how python works.
Now, if e is mutable, say a list, you can do
e.append(blah)
and, since the name 'e' is not being rebound, you would see the change
in 'sequence'.
