How do we know that this returns an InstanceMirror (seeing that it returns the
arg)? What's the intended behavior? Is the type annotation just wrong?

The method "reflect" always returns an InstanceMirror, and arg is supposed to be
a non-mirror'ed instance.

-    _invoke(
-        fieldName, JSInvocationMirror.SETTER, 'set\$${n(fieldName)}', [arg]);
+    String reflectiveName = '${n(fieldName)}=';
+    String mangledName = JsMirrorSystem.reflectiveNames[reflectiveName];
+    _invoke(s(reflectiveName), JSInvocationMirror.SETTER, mangledName, [arg]);
     return reflect(arg);
   }
 
   InstanceMirror getField(Symbol fieldName) {
-    return _invoke(
-        fieldName, JSInvocationMirror.GETTER, 'get\$${n(fieldName)}', []);
+    String reflectiveName = n(fieldName);
+    String mangledName = JsMirrorSystem.reflectiveNames[reflectiveName];
+    return _invoke(fieldName, JSInvocationMirror.GETTER, mangledName, []);
   }
