    Attempt to use a faster exception value for return type annotations that check for exceptions. · a3ffd72f

    Inside of a module, it is safe to convert a function declared
        cdef int func() except *:
        cdef int func() except? -1
    because a) we need an exception return value anyway and b) there will always be an explicit exception check afterwards. Thus, changing the function implementation itself is safe. We must exclude functions that are only declared but not implemented since we do not control their signature and it is not safe to assume a specific exception return value if it is not declared.
