Why FIXME?

Let me make that more explicit.

The arity checking is not correct when spread params are present. The number of
required arguments for func4 should be 1 and not 2.

 
   let func5 = (p1, p2) => { p1; p2; };
-  func5();
+  func5(1, 2);
 
   let func5b = p1 => p1;
-  func5b();
+  func5b(1);
 
   function func6() {
     var1, var2a, var2b, var2c;
