There's nothing that pipes or partials do that you couldn't emulate in user-space today (really, since 5.3 is you really wanted to). The emulation is just butt-ugly and slower, which is why most people don't do it except in very specific cases or if they have a user-space library available that makes it slightly less butt-ugly. The purpose of PFA and pipes (and short functions, and auto-capture closures, and basically everything else I've been talking about all year) is to make those things prettier and as fast as reasonable, which makes using those techniques more natural. Once you start down that path, though, there's really no usable solution before you get down as far as... PFA and Pipes in their current form. --Larry Garfield
