(load "foo") is legal Clojure; if a tool can't handle it, that's either a
bug or a deliberate limitation in the tool. In the case of slamhound, I
guess it's a deliberate limitation. On the other hand, when I followed the
instructions on the slamhound page and ran it against my directory it
overwrote helpers.clj from
(defn- hello [] (println "Hello "))
to:
(ns hello)
which looks like very rude behavior to me - I won't be using slamhound
anytime soon. So I wouldn't say that using "load" has side-effects that
break tools, but that some tools may make assumptions and have side-effects
that do nasty things to legal code (or "encourage" a particular style). I
would not be surprised if other tools make similar assumptions about the
structure of clojure source files. Then it's a question of whether one
wants to allow the limitations of tools to constrain one's use of the
language.
