Is a Python list guaranteed to have its elements stay in the order they are inserted in?
...plicitly made to do so. stacks and queues are both types of lists that provide specific (often limited) behavior for adding and removing elements (stacks being LIFO, queues being FIFO). Lists are practical representations of, well, lists of things. A string can be thought of as a list of characters,...
Start thread with member function
...std::thread with a member function that takes no arguments and returns void . I can't figure out any syntax that works - the compiler complains no matter what. What is the correct way to implement spawn() so that it returns a std::thread that executes test() ?

for example (using reflector):
static int Test() {...
