dbc:

I have a CL that addes MUST_USE_RESULT to all functions in elements.h that
return a MaybeObject*.


https://chromiumcodereview.appspot.com/10209027/diff/3001/src/objects.cc
File src/objects.cc (right):

https://chromiumcodereview.appspot.com/10209027/diff/3001/src/objects.cc#newcode8508
src/objects.cc:8508: accessor->CopyElements(this, new_elements,
new_elements_kind);
Missing check for failure? CopyElements has a MaybeObject* return type.

https://chromiumcodereview.appspot.com/10209027/diff/3001/src/objects.cc#newcode9408
src/objects.cc:9408: ValidateElements();
Maybe check result for failure before calling ValidateElements?
