// So, 'suspend' returns control to the place from which it was
|
|
// called (the "call site"). How do we control back to the
|
|
// suspended function?
|
|
//
|
|
// For that, we have a new keyword called 'resume' which takes an
|
|
// async function invocation's frame and returns control to it.
|
|
//
|
|
// fn fooThatSuspends() void {
|
|
// suspend {}
|
|
// }
|
|
//
|
|
// var foo_frame = async fooThatSuspends();
|
|
// resume foo_frame;
|
|
//
|
|
// See if you can make this program print "Hello async!".
