Thanks puzzler for the explanation. I tried out your `unchunk` and its works nicely..
I then googled around about chunk and memory issues.. I found most issues about chunking and stack overflow.. here.. https://stuartsierra.com/2015/04/26/clojure-donts-concat [which is very good read for this question as well.. the diagram of lazy-seq's is great.] with https://groups.google.com/forum/#!topic/clojure-dev/ewBuyloeiFs/discussion [Left recursion with concat as said in above article as well would stack overflow]. However, none talked about memory consumption.. Do anyone know about good practices with `chunking` and `memory consumption` ? *Can i say that : as long tail of recursive calls are happening due to chunking.. all the memory of intermediate steps is present at the same time.. leading to heavy memory usage.. ?* or is it something more subtle.. Some graphs that i found while profiling : <https://lh3.googleusercontent.com/-E2PFxgZcXTc/Vw6GI9F_jtI/AAAAAAAAAKU/z8iwE3LYct8EGqSXuETR-yrHUCvDIolywCLcB/s1600/long-recursive-concat-map-calls.png> -- You received this message because you are subscribed to the Google Groups "Clojure" group.
