I use the following at the beginning of the sub, so I can still use $self, and someone can override the functions in a derived class, if need be. (it won't work with your exact calling syntax though, as it's mostly for items that don't require values from the actual object).

sub function_name {
    # for a function call
    my $self = __PACKAGE__;
    # for a method call
    $self = shift if UNIVERSAL::isa( $_[0], __PACKAGE__ );
    ...
}

You could also write do the shorter, more efficient, but potentially more confusing :

sub function_name {
    my $self = UNIVERSAL::isa( $_[0], __PACKAGE__ )
        ? shift : __PACKAGE__;
    ...
}
