However, you have to reverse the list

You should probably inline comp for your purposes. Note the reverse call
there.
Hi Meikel,
Thank you for pointing it out that 'comp' calls 'reverse' internally.
I've been calling 'reverse' twice.
Appreciate you so much.
I'll try 'comp'ing the accumulated functions manually without 'reverse'.

Providing a timeout of Long/MAX_VALUE is functionally equivalent to having no

Hi,
the following code is an example from a Clojure book. It defines a macro
named vmap that can work like map but with changed parameters:
(defmacro vmap [coll f] '(map ~f ~coll))
Now I try to use it:
(vmap [1 2 3] inc)
#CompilerException java.lang.Exception: Unable to resolve symbol: f in
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))
