What's the difference? What your example is saying basically is that
the shell is treating the "1 $aa 2 3" as a single parameter (i.e. spaces
do not have the usual parameter-separating behaviour), _but_ variables
are interpreted. Using '' prevents variable substitution, so
> ~$ perl -e 'print join(",",@ARGV), "\n";' '1 $aa 2 3' 4 5 6
should give
1 $aa 2 3,4,5,6
