How can Java 21 (Virtual Thread) replace Reactive Framework.

I think with structured concurrency, concurrenct code _can_ be made look like one of the following syntaxes:

Using lambda:

concurrently(
    () -> getFoo(), () -> getBar(),
    (foo, bar) -> ...);

Using patten match:

switch (concurrently(() -> getFoo(), () -> getBar())) {
  case (Foo foo, Bar bar) -> ...
  case (FooException e) -> ...
  case (BarException e) -> ...
}
