In this case "outlet_anything(my_outlet,gensym("list"),4,t); " is better ;-)

The  t_symbol *s argument is ignored if it's "gensym("list")" but is 
bounded to the list if it's different.

t_atom t[4];
SETFLOAT(t[0],2);
SETFLOAT(t[1],3);
SETFLOAT(t[2],5);
SETFLOAT(t[3],7);
outlet_anything(my_outlet,gensym("floatList"),4,t);

will output :

floatList 2 3 5 7

on my_outlet. You can then route it as you want without mixing it with 
other lists ;-).

Bye,

Nicolas
