Re: The case for as->> ("as-last")

Oh happy day! :-D Today I was looking at some clojure code on using core.async with ClojureScript [1], and the example used this strange "as->" expression that I'd never seen before (I'm from the 1.2 era, just getting back into the Clojure game), and I was trying to figure out what the heck thi

Fair enough. Now I'm beggining to truly appreciate as->, thank you. I still believe as->> would be somewhat useful but I don't see it getting added to clojure.core now. On Mon, Feb 18, 2013 at 9:10 PM, Marko Topolnik wrote: > as-> is meant to be used as the only threading form. In your example yo

The case for as->> ("as-last")

While there are other possible uses (example), I see myself mainly using as-> as a mechanism for resorting to thread-last within a thread-first expression. For example, given (-> [[1 1 1] 2 3] (nth 0)) I might want to add an operation th
