It's valid if you make them function calls.
user=>
(-> "test-string-with-lots-of-dashes"
((fn [x] (s/split x #"-")))
((fn [y] (interleave y (range))))
((fn [z] (s/join #"_" z)))
((fn [z] (s/join " * " ["I am serious" z "Not Kidding!!" z]))))
"I am serious * test_0_string_1_with_2_lots_3_of_4_dashes_5 * Not Kidding!!
* test_0_string_1_with_2_lots_3_of_4_dashes_5"
