I wouldn't think there would be, given that filter() in general is specified to filter the whole sequence. I would in no way _object_ to a first-available() that's guaranteed to stop as soon as it gets a true() result from $function. And there's obviously a point past which one doesn't want to keep chaining "otherwise". Frequency of the use-case might still be questionable. -- Graydon Saunders | graydonish@xxxxxxxxx ^fs oferiode, pisses swa mfg. -- Deor ("That passed, so may this.")
