Ha! Look again! you gave eval 2 args (x and the list), not one!
Also, proc x {args} is a very special case of "args". Try your test with
proc x {var} and the eval test will fail. When the last arg of a proc is
"args", it _combines_ all remaining args into a list. Hmm, this is the
opposite of your original question about magic splitting. Magic
_combining_ does exist!
