Raymond Hettinger <rhettinger at users.sourceforge.net> added the comment:
This has been rejected before. The core issue is that it is not a very useful operation because it consumes the iterator.
Also, this isn't an operation worth optimizing because most iterators that do something interesting are already slower than a genexp inside a sum().
