dynamic-wind is nice because it guarantees that the pre- and postconditions for a chunk of code will be run regardless of continuation jumps, exceptions, etc. The only issue I have is that the three thunks do not share scope, making it difficult to do setup/teardown workflows. I feel like I should be able to make this work with nested dynamic-wind or with-handlers but haven't been able to get there without losing the guarantee of running. Is there a way?
Example of what I'd like to do: (my-dynamic-wind (thunk (define conn (connect-to-server))) (thunk (send-message conn "foo")) (thunk (finalize-connection conn))) -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
