What is the difference between packaged_task and async
...nces if you use a rather long function, such as
//! sleeps for one second and returns 1
auto sleep = [](){
std::this_thread::sleep_for(std::chrono::seconds(1));

... deferred until the parameter is known. It's called two-phase compilation, and MSVC doesn't do it but it's required by the standard and implemented by the other major compilers. If you like, the compiler must compile the template as soon as it sees it (to some kind of internal parse tree representat...
Are class names in CSS selectors case sensitive?

But HTML class names are case-sensitive (see the attribute definition), and that's causing a mismatch in your second example. This has not changed in HTML5.1
