// This example illustrates a case we wish to do better in terms of inlining and
// code generation.
//
// Today this function is 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)
//
// See #25478 for ideas on how to make this better.
