let's add a short comment explaining what this is meant to test, for example:

"nSM may print the interceptor instead of the receiver, it should always print
the receiver."

+
+import 'package:expect/expect.dart';
+
+class N {
+  noSuchMethod(i) { print('x'); return 42; }
+}
+
+get NEVER => new DateTime.now().millisecondsSinceEpoch < 42;

or use @NoInline() @AssumeDynamic() ?

+
+main() {
+  var c = 12345;
+  if (NEVER) c = new N();
+  var e;
+  try {
+    c..toString()..add(88);
+  } catch (ex) {
+    e = ex;
+  }
+  var s = e.toString();
+  Expect.isTrue(s.contains('$c'), 'Text "$s" should contain "$c"');
+}
