Yes you would have to program in a subset of python. But type annotations are not always needed. For the array I do a little hackery. You can define the array

Yes you would have to program in a subset of python. But type annotations are not always needed. For the array I do a little hackery. You can define the array without an initial value in the container and I can guess the value type. arr = [] arr.append(1) it will spit out std::vector<decltype(1)> arr{}; arr.push_back(1);
