user=> (defn foo [] (throw))
#'user/foo
user=> (foo)
NullPointerException user/foo (NO_SOURCE_FILE:1)
user=> (defn bar [] (throw Exception baz))
#'user/bar
user=> (bar)
ClassCastException java.lang.Class cannot be cast to java.lang.Throwable user/bar (NO_SOURCE_FILE:1)
; This one works, but ignored-symbol, should probably not be ignored
user=> (defn quux [] (throw (Exception. "Works!") ignored-symbol))
#'user/quux
user=> (quux)
Exception Works! user/quux (NO_SOURCE_FILE:1)Approach: Count forms and throw an appropriate exception if arity != 1.
