Maybe a general tip for macro design: if you want one or more bindings, see if you can't make the macro simply stick these into an existing binding-using form, like let, loop, if-let, etc. (I cheated: rather than manually working around this bug, I used when-let > which already does the right thing.) > It's not cheating to build on existing, useful library functionality. And when you can, it's silly not to. I just wish I'd thought of it first. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
