Few thoughts:
1. You're using a type test there. I'd check out the Collections
section of the cheatsheet: http://clojure.org/cheatsheet
2. While I would very much expect the type test (coll? seq?) to return
false on a string, I would _not_ expect the capability test
(sequential?) to return false, and it does for a String. Is this the
expected behavior? I would think that any seqable would return true
for sequential?. What do we think? Then, at least, you could easily
write code that expects to process only seqable things with a simple
pre-condition that the argument is sequential?.
