[PD-dev] how to output list with selector

[Alexandros Drymonitis]

That's what I need, indeed. I can't get my head around how to create the 
selector symbol though. The second argument to outlet_anything is a 
pointer to a t_symbol, but how do I get a pointer to a "foo" symbol?

I've tried `t_symbol *s = atom_gensym("foo")` but I get a warning the 
atom_gensym() expects a const t_atom *a, and when I pass `s` to the 
second argument of outlet_anything and print the output, I get "???" 
instead of "foo". This might be obvious, but it's quite complicated to me.
