Alright, here it goes: 
$_='Just';
$_='"...erxpnU;yerC;erugban;gfhW"gavec';

Easy to see, just setting $_ to something, then resetting it. 
$-='another Perl';

[download]
Useless; $- is the number of lines left on the page of the currently selected output channel, and cannot be a string value (or a negative value). $- remains zero after this asignment. 
y/\\abcdefghijklmnopqrstuvwxyz ;
/'nopqrstuvwxyzabcdefghijklm                    /;

[download]
A simple translation on $_: Now the value is almost the reverse of "print "Just another Perl hacker..."", we just need one more translation to get it there: 
$-='Hacker'; #again, this is just filler
y/!!ABCDEFGHIJKLMNOPQRSTUVWXYZ       ;
/''NOPQRSTUVWXYZABCDEFGHIJKLM /;  #here's that translation I spoke of

[download]
Now, the string is ready to be eval'ed 
eval reverse  $_;

[download]
Again, this is just filler, it evaluates to a string, which is a true value, but does nothing. 
''.''.''.''.''.'print "Just another Perl Hacker"';
