Yes.
Creating a new project in Lein then opening it in Light Table and with
minimal edits:
(ns test.core)
(defn bar [a b c])
(defn foo
"I don't do a whole lot."
[a b]
((let [y (bar(a b))]
(println a b "Hello, World!"))))
foo evaluates without error despite calling bar with too few parameters.
I suspect in my code next-to-play is messing up the stack because it pulls
3 parameters off the stack when only 2 have been placed on it.
