Imagine that you specify interfaces left to right in order of importance, and therefore when a generic function is defined for two of them the leftmost one wins. Should you happen not to remember though you can quickly try out an example at the REPL. I do that all the time in Python when I want to verify that what I remember is in fact correct. -- Cosmin Stejerean http://offbytwo.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
