Also good to know, thanks.

For posterity, it's worth noting that you can use the Boost Coroutine library to implement this in C++ in a nice object-oriented fashion to make a loop that executes Racket tasks in a way that doesn't require bouncing your `main` through `scheme_main_setup` or equivalent, which is great if you're embedding a racket interpreter to be reused as an API rather than a one-off program. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
