 I suppose someone should point out that, taken literally, "$p" does
have the same effect as "w | tail +3 ".

% set p="w | tail +3 "
% "w | tail +3 "
w | tail +3 : Command not found.
% "$p"
w | tail +3 : Command not found.

 Of course this wasn't what you intended, but it also demonstrates that
quoting does effect the meaning of shell commands.
