It's not buggy and yet docs are all ok :-)
Look - head is a function - it returns its value. If you don't assign the value to any
word - it just returns its value to console :-)
->> head? ["a" "b" "c"]
== true
->> head? tail ["a" "b" "c"]
== false
->> head? head tail ["a" "b" "c"]
== true
here head? checks for the returned value ....
Andrew is right, just reassign the value of word referring to series ...
