• 0x20000000 Optional (?).

• 0x40000000 Variable length argument (...).

• 0x80000001 Not evaluated (!).

Example

    Gamma> function_args(getprop);
    ((symbol 0) (property 0))
    Gamma> function_args(drain);
    ((file 0) (t_or_nil 0))
    Gamma> function_args(gc);
    nil
    Gamma> function_args(defvar);
    ((symbol -2147483648) (value 0) (constant? 536870912))
    Gamma> function_args(read);
    ((file 0))
    Gamma> function g (a,b,c) {((a * b)/c);}
    (defun g (a b c) (/ (* a b) c))
    Gamma> function_args(g);
    ((a 0) (b 0) (c 0))
