lists vs. anything? Re: [PD] trigger

Hi Larry,

The reason for "list" is so that messages can all have a symbolic selector;
so that, if you type "1 2 3" into a message box, the actual message is
"list 1 2 3".  However, you can type "list" explicitly if you want, and if you
want to have a list starting with a symbol, like "dog 1 2 3", you have
to type "list dog 1 2 3"; otherwise the selector would be "dog" and the 
arguments "1 2 3".

The reason every message isn't "list" is so that you can have objects that
take lists but also take other messages -- pipe, for instance, delays lists
but also has a "flush" message.

There ought to be objects that just convert "list" to arbitrary messages and
vice versa.  I'm scared in general to add features like that without checking
how Max does it first...  next time I get close to a MacIntosh I'll try to
get a plan together...
