Other than the future work on the error trait discussed above, there is future work to be done on the backtrace type. In particular, the backtrace type currently provides no method of analysis other than debug and display printing the backtrace. It would be beneficial to provide a platform agnostic, standard API for iterating over the frames of the backtrace and the members of the frames in the long term. Such an API would justify a separate RFC.
