Currently, to retrieve the Arguments of a function on the call stack, we assume that the call stack contains an explicit entry for that function. This won't be the case if the function is inlined. Call stack walking for the purpose of JS-visible reflection should be able to rematerialize call frames of inlined functions, and arguments retrieval should be hardened for this possibility.
