This snippet of Clojure code prints out aFOObFOOcFOO. Note that Clojure arguably does not fully satisfy the fourth point on your list, since read-time is not really open to user code; I will discuss what it would...
Good examples of Not a Functor/Functor/Applicative/Monad?
...fied. For example, fmap id ≠ id, because let (Q(f,_)) = fmap id (Q(read,"123")) in f "456" is 123, but let (Q(f,_)) = id (Q(read,"123")) in f "456" is 456.

http HEAD vs GET performance

For example, suppose you want to check if resource 123 exists. A 200 means "yes" and a 404 means "no":
HEAD /resources/123 HTTP/1.1
