     # Returns
-    - If `returnJulia` is `false`, returns a Mathematica MathLink object representing the result of the Mathematica function.
-    - If `returnJulia` is `true` (default), returns a Julia expression representing the result of the Mathematica function.
+    - If `returnJulia` is `Val(false)`, returns a Mathematica MathLink object representing the result of the Mathematica function.
+    - If `returnJulia` is `Val(true)` (default), returns a Julia expression representing the result of the Mathematica function.
