AFIC, qw() allows you to separate the entries with whitespace. That's pretty convenient. Look at this: 
$ perl -e 'print join(", ",qw(1 3 6 2));'
1, 3, 6, 2

But trying that without the qw gives: 
[jeroen@rulffk]  perl -e 'print join(", ",(1 3 6 2));'
Number found where operator expected at -e line 1, near "1 3"
    (Missing operator before  3?)
syntax error at -e line 1, near "1 3"
Number found where operator expected at -e line 1, near "3 6"
    (Missing operator before  6?)
Number found where operator expected at -e line 1, near "6 2"
    (Missing operator before  2?)
Execution of -e aborted due to compilation errors.

Hope this helps.
