We've expanded our Perl news coverage and improved our search! Search for all things Perl across O'Reilly! Joshua Gatcomb
Joshua Gatcomb's job title is "Information Technology Specialist" which is a glorified way to say general problem solver. One of his favorite ways to solve problems is through Perl which he does as often as he can. He believes strongly in giving back to the Perl community by answering questions and spreading advocacy in various forums. While he only has one module on CPAN (Tie::Hash::Sorted), he also helps out with Pugs and Parrot by contributing tests, code examples, utilities, and bug reports. Understanding and Using Iterators Unlike some other programming languages, Perl makes it easy to process lists of items. Lists and arrays aren't always suitable for every task, though; sometimes you need something more powerful. Sometimes you need an iterator. Joshua Gatcomb explains where iterators are useful and how to use them. [Jun 16, 2005]
