Clojure to die for

If you use clojure.typed, I think the second example would give you a compile-time type error.

[ Parent | on HN ]

While true, the second example already gives you a compile-time error in normal Clojure (note the CompilerException). It never compiled and was never evaluated. This on the other hand compiles and is likely what the OP wanted to show:

  user> (let [e nil] (e :key))

  NullPointerException
