+// 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.

+//     resume foo_frame;
+//
+// See if you can make this program print "Hello async!".
