for(ref bless[],just'another'perl'hacker){s-:+-$"-g&&print$_.$/}

This exploits the old perl 4 syntax for packages. just'another'perl'hacker is the same thing as just::another::perl::hacker, so what you are doing is blessing an arrayref (which could be just about anything legal, it doesn't matter) into an object that is returned to:

for(ref bless[],just'another'perl'hacker){s-:+-$"-g&&print$_.$/}

Which promptly returns the name or type of the object, in this case "just::another::perl::hacker".

The for "loop", is just a nice way to put something into $_ and do stuff on it. It could just as well be:

$_ = ref bless[],just'another'perl'hacker;
s-:+-$"-g&&print$_.$/

Then, a substitution takes out all the '::' and replaces it with $", which by default contains a space:

for(ref bless[],just'another'perl'hacker){s-:+-$"-g&&print$_.$/}

Is the same as

s/:+/ /g

And, since this returns true (it matches), the next statement after '&&' is also executed, and prints what we have left plus a line ending (the content of $/).

Nice. That will work as your signature. :)
