Do you think you'll need to try to identify the order that the events were created in? What if user A does: $ touch file.txt $ rm file.txt And what if user A had separately done: $ rm file.txt Error: file not found $ touch file.txt Would those operations both potentially create File-Create P

Re: [racket-users] Would it help to call racket2 something else?

If "racket" is related to "scheme" by being an illegitimate scheme, I think "cartel" could be a good choice for "an even more illegitimate scheme". Plus, it's almost an anagram of racket. #lang cartel -- You received this message because you are subscribed to the Google Groups "Racket Users"

Thanks for the feedback. I will check to see if there's some way to query for capabilities, but I doubt it, given the client code. The client code does most of this version checking in one class, so that seems localized enough and I think it will be straight forward. Maybe if I stumble on a
