Indeed it is:

% print -rl -- '"foo bar"' '' 'baz' | xargs  
foo bar baz
% print -rl -- '"foo bar"' '' 'baz' | perl -012l040pe1; echo
"foo bar"  baz 
%

Not bad for a one-byte program :-)

Cheers,

Daniel
(The final «1» is the only byte of Perl source code in that invocation;
it's the argument to the «-e» flag.)
