Nice one! Implicit evaluation of a used confusingly. Took me a little while to figure how you got the text inside $_ and the qw) trick is very ingenious too. A fine example of how beautiful perl can be :)

Tips for the hopeless:

• qw) starts a string that terminates at the next ) so actually the whole script is stuff assigned into @j!
• the definition of @j stops at the second comma on line 5, so the rest is evaluated but not assigned anywhere!
• the s""@j," puts @j into $_ and then the 's (" )))g' (which is actually s/" //g in disguise!) eliminates some (non-existant?) quotes
• Finally, we get a 'print' that spews out $_ beautiful!
