proxy inlets that take symbols or lists that start with symbols?

    Is there a way to have an inlet take in an arbitrary symbol, or a list that starts with a symbol? It seems that proxies that take in lists only accept lists that start with a number. Lists that start with symbols trigger a "doesn't understand "g"" error, where g is the first symbol in the list.
    (A set of external examples in the SDK that demonstrate different kinds of proxies (lists, symbols, etc) would be so helpful!)

      Hi there, it's actually pretty simple and I don't think external examples are needed. Here is how you ought to think about it: when you create a proxy inlet you create a general inlet that is able to accept any message selector, whether numeric (A_LONG or A_FLOAT) or a symbol (A_SYM). It doesn't matter if the message is made of a single atom or a list of atoms. You gotta look at the message selector only. (basically the first atom in a list)
      You need to implement two methods in your object, a "list" method and an "anything" method,
      class_addmethod(c, (method)yourobject_list, "list", A_GIMME, 0); class_addmethod(c, (method)yourobject_anything, "anything", A_GIMME, 0);
      The "list" method will be called in response to all lists that start with a numeric value. The "anything" method will be called in response to all lists that start with a symbol. You won't receive any more "doesn't understand xxx" errors. That's it.
      Hope this helps.
