Can you find an equivalent issue in Convex Lisp? Need to know what form is failing... currently (when-let) and similar seem to return regular ARITY errors.

[billbsing]

If you do when_let() instead it fails correctly as the same as convex-lisp (when-let), so I think it is the parsing of the - symbol and passing the statement directly over to convex-lisp
