It's an insight I was missing too -- continuations are often *invoked* in general directed-graph fashion, and before Christian said that I hadn't realized the *implementation* never sees anything worse than a tree. So next time I see Christian, I'll punch him hard in the stomach, and mumble "good job" loudly enough so that he hears it, but indistinctly enough so I can plausibly deny it in case any other guy overhears us. *That's* the American Way <wink>. first-it's-hugging-then-it's-song-contests-ly y'rs - tim
