 Really convenient!
 
+From the second function -- which calls back to Lisp -- we can see that it
+suffices to simply pass some intuitive, primitive C++ values to `ecl_fun`,
+which will be converted automatically (using `QVariant`) to the appropriate
+Lisp values.
+
+**Conclusion**: by only allowing `QVariant` arguments for calls between Lisp
