Well, it does nothing if and only if there's nothing in argv.

% for x y z; echo ". {$x} / {$y} : {$z} ."
% set a b c d e f g h i j k l
% for x y z; echo ". {$x} / {$y} : {$z} ."
. {a} / {b} : {c} .
. {d} / {e} : {f} .
. {g} / {h} : {i} .
. {j} / {k} : {l} .
%

So it's valid and does something useful, iterating in tuples across the
"$@" array.
