If you use Coro with Perl, you can say something like:

  async {
    do_something;
    cede;
    do_something;
  }

  do_something_else;
  cede;

See http://search.cpan.org/dist/Coro/Coro.pm for more information.

[Edit: If you want to see a continuation-based web framework built with Coro, look at Continuity: http://search.cpan.org/~awwaiid/Continuity-0.994/lib/Continu...

It's very cool.]
