Well, if that is true, then I think the correct solution is to also dispatch on the current connection type, to do the right thing for each kind of back end.
This would be easy if the current connection was known to be held in a special variable, say, *database*. :-) I will "fix" for my special case in my own code base, but this not seem to me to be a "correct" solution for an important system library. -- Alain -- <http://www.gocatch.com/> Sydney, Australia <https://www.facebook.com/goCatch> <https://twitter.com/gocatchapp> <http://www.linkedin.com/company/goCatch> <https://itunes.apple.com/au/app/gocatch/id444439909?mt=8> <https://play.google.com/store/apps/details?id=com.gocatchapp.goCatch&hl=en> -- You received this message because you are subscribed to the Google Groups "Clojure" group.
