-// // This example illustrates a case we wish to do better in terms of inlining and
-// // code generation.
-// //
-// // Naively this function would be compiled without inlining Wrapper.[],
-// // JSArray.[] and Wrapper.[]= because:
-// // JSArray.[] is too big (14 nodes)
-// // Wrapper.[] is too big if we force inlining of JSArray (15 nodes)
-// // Wrapper.[]= is even bigger (46 nodes)
-// //
-// // We now do specialization of [] and []= by adding guards and injecting builtin
-// // operators. This made it possible to inline []. We still don't see []= inlined
-// // yet, that might require that we improve the inlining counting heuristics a
-// // bit.
