Most of it is noise, but I filtered out a few mails from Sara and Rasmus as they probably are of most interest: http://markmail.org/message/xzhdhbjozb4yrhh3 http://markmail.org/message/ryhygtimpd7q2nok http://markmail.org/message/32fklwqykpk56iph http://markmail.org/message/w2kbh7psplnmctcr >> yield: Yields the value null with an auto-incrementing integer key. > > What is the usecase for this? Use case is $data = yield;. In that case you don't care about what you yield (so just the default value and key are yielded), you are only interested in what you get sent back. Nikita
