It also resembles a waterfall (not very friendly term in our
profession, but fits well in this case) where the result of an earlier
computation is passed on down the stack. It also works very similarly
to the
Just nitpicking, but for me those thread-first/last operators beg for "proper"
formatting with newlines and indentation to emphasize the "threading", like
not:
(-> 2 (* 5) (+ 3))
but:
(-> 2
(* 5)
(+ 3))
also as mentioned before, using thread-first and thread-last to name those

I couldn't resist.
#(+ % 1) == inc
#(+ % 2) == (partial + 2)
They give much better-looking functional program. Hope you forgive me :-)

Very nice!
One little problem I had while learning this operator was realizing that it
was a macro and not simply a form of function composition (like an inverted
'comp'). So to convert something like
((comp #(+ % 1) #(+ % 2)) 0)
to use thrush you would need to write
(-> 0 (+ 2) (+ 1))
and N
All fantastic comments...I was thinking why didn't i use - instead of plus!
I'll fix these up soon.

Additional to all the positive comments, I'd suggest you use an
operator which is not commutative, otherwise the differences between
-> and ->> are less evident.

This is all very nice but it seems to me to be a case of less is more (or
more is less). I mean, if I am used to read inside out easily, this
operator just makes my life harder. I don't plan to use it but
unfortunately to understand other people's code, I have to switch mindset.

Noted and updated! Thx.

Technically speaking, the -> & ->> macros are _not_ the thrush
combinators. Fogus wrote about them sometime back
http://blog.fogus.me/2010/09/28/thrush-in-clojure-redux/ and I think
you should mention that in your document too.
Nevertheless, very useful document!

I created a tutorial explaining what the thrush -> and ->> operator is.
https://github.com/ftravers/PublicDocumentation/blob/master/clojure-thrush.md
My tutorials are aimed at people who appreciate VERY explicit explanations,
which I think there is a bit of a gap among current internet available
