This has me thinking about doing Node.JS-style event processing with the new C++ lambda syntax. I guess you can do it, but you must always copy [=] into the closure so that the io function can return: void fred() { int first = 'x'; int second = 'y'; wait_key([=](int c) { if (c == x) { wait_key([=](int d) { if (d == y) { printf("got x and y\n"); } }); } }); } wait_key(void (*func)(int c)) registers a callback then returns. When a key is processed func is called.
