When you call a class method (for example my $obj = MYObject->new), the class name is automatically passed in as the first element of @_. A similar thing happens when you call object methods, the object is passed in as the first element of @_.

For more details see perlboot, perltoot, perlobj and Damian Conway's book Object Oriented Perl.
