I've always tended to see a so-called "meta-message" as being a selector 
symbol followed by a list, rather than as a list in which the first 
element has been taken out to be the selector. After all, in 
implementation, this is respectively selector,argc,argv versus 
argv[0].a_w.w_symbol,argc-1,argv+1 and the first one is more direct. The 
latter is what [list trim] does.

What Pd's message parser does tends to add to the confusion, as messages 
starting with a non-symbol are accepted and taken with an implicit "list" 
selector, and as some objects (but not all) take anything() such that any 
"meta-message" is "untrimmed" into a list... this is mostly limited to 
[pack] and [list] afair.
