+1 for this one question to discuss is how while should be expressed Chris has predicate on accumulator and next element, my implementation takes predicate on accumulator only https://github.com/jozic/scalax-collection/blob/master/src/main/scala/com/daodecode/scalax/collection/extensions/package.scala#L81

search on github reveals people do similar things: predicate on accumulator

• https://github.com/valdisxp1/cvs-git_bridge/blob/master/src/main/scala/com/valdis/adamsons/utils/LazyFoldsUtil.scala#L12
• https://github.com/dbisUnibas/ADAMpro/blob/master/src/main/scala-2.10/ch/unibas/dmi/dbis/adam/index/structures/va/marks/EquifrequentMarksGenerator.scala#L143

something in between, predicate on acc and element, returning boolean

• https://github.com/jlln/Zisa/blob/master/lib/org/saddle/vec/VecImpl.scala#L67
• https://github.com/dhgarrette/ccg-supertagging-2014/blob/master/src/main/scala/dhg/util/CollectionUtil.scala#L830

another way to look at it https://github.com/mvv/scala-extras/blob/master/src/main/scala/scalax/Data.scala#L226
