in reply to Calling subs with &

You can also use & for evil purposes like using reserved words as sub names. It's not bad for obfuscation though. 
use strict;
&use();
#use(); #this doesn't work
sub use
{
      print "In sub\n";
}

    package Just_another_Perl_Hacker; sub print {($_=$_[0])=~ s/_/ /g;
                                      print } sub __PACKAGE__ { &
                                      print (     __PACKAGE__)} &
                                                  __PACKAGE__
                                            (                )
