-Description: Perl implementation of iterators
- Iterator is meant to be the definitive implementation of iterators, as
- popularized by Mark Jason Dominus's lectures and recent book (Higher Order
- Perl, Morgan Kauffman, 2005).
- .
- An "iterator" is an object, represented as a code block that generates the
- "next value" of a sequence, and generally implemented as a closure. When you
- need a value to operate on, you pull it from the iterator. If it depends on
- other iterators, it pulls values from them when it needs to. Iterators can be
- chained together (see Iterator::Util for functions that help you do just
- that), queueing up work to be done but not actually doing it until a value is
- needed at the front end of the chain. At that time, one data value is pulled
- through the chain.
