Summary of the work here as I pass through :)

Files already done:
    Objects/memoryobject.c: converted to signatures without Arg Clinic (Py 3.5)
    Modules/_opcode.c: Issue 19674 (3.4). Only one function I can see there (Larry’s original post says two sites).
    Modules/_io/_iomodule.c: part of Georg’s modules_issue20186.patch, but already handled in Issue 20175 (3.5)

    Modules/_operator.c: patch by Tal, ready for commit?
    Modules/_lsprof.c: Georg’s modules_issue20186.patch
