To make up for my total misunderstanding of what you were asking before, I hereby offer you the Plumbing module, available here: https://bitbucket.org/mtnviewmark/haskell-playground/src/2d022b576c4e/Plumbi... With it, I think you can construct the kinds of pipelines you describe with the composition aspects you desire:
:load Plumbing.hs [1 of 1] Compiling Plumbing ( Plumbing.hs, interpreted ) Ok, modules loaded: Plumbing. let filterUntil cond start end = (passUntil (>=start) =|= pfilter cond) =+= passWhile (<end) let filterUntilPlus1 cond start end = filterUntil cond start end =+= pass 1 filterUntil even 10 15 `pump` [1..] [2,4,6,8,10,11,12,13,14] filterUntilPlus1 even 10 15 `pump` [1..] [2,4,6,8,10,11,12,13,14,15]
