Disclaimer: noobish advice I don't understand why it concerns you that the foreach pushes to an array. It's scoped within the subroutine so I don't think it's particularly inefficient. Because you push twice to the output array, a map is difficult to pull off while preserving the overall flow of information. This probably occcurred to you. The remaining duplicated code seems natural to me to leave as-is. Wrapping it up in a subroutine seems like overkill; you weren't considering THAT, were you? I think the function is stunning, BTW. I'm still wrapping my head around it. One may be able to make its workings more obvious, but I can't help you, as I barely follow how it works. Perhaps my self-declared confusion will prompt some of the Enlightened to elaborate. ry
