Description Sebastian Zarnekow CLA 2012-02-08 16:37:03 EST 
It may be useful to have something like

takeWhile(Iterable, Predicate):Iterable
dropWhile(Iterable, Predicate):Iterable

Having some generator functions would be nice, too, e.g. one could write

val initial = 1
val Iterable<Integer> iterable = initial.seed [ int i | i * 2 ]

to generate an infinite sequence 1, 2, 4, 8, 16...
Comment 1 Knut Wannheden CLA 2012-02-09 03:19:48 EST 
+1. There is also a Guava feature request for takeWhile and dropWhile: http://code.google.com/p/guava-libraries/issues/detail?id=477
