Subject [jira] Commented: (IO-181) LineIterator should implement Iterable
Date Wed, 19 Aug 2009 05:31:16 GMT


Robert Collins commented on IO-181:

Henri only noted that there is a Iterable->Iterator relationship. It's a fairly common
idiom in python to have single-pass Iterables (like files) allow iteration on this.

You can even separate out the Iterator code from the Iterable in those situations if needed.

I think it would be lovely if this was reopened (I'd be happy to write the patch) - contrast:
try {
