Thanks to all for responses.
I just wanted to use that in higher-order composition in mind, not to
construct any data structures.
I have tweaked a bit the function:
(defn conr[ col item ]
(lazy-seq
(if (seq col)
(cons (first col) (conr (rest col) item))
(list item))))
And now stick with it.
All works as desired:
(conr (conr (conr '( 1 2 3) 4) 6) 7)
(1 2 3 4 6 7)
