I have a class called XYZServer that I want to use to intercept (and divert) calls to another package my XYZServer package looks like this.... 
sub new
{
        my $proto = shift;                      # Get the Prototype
        my $class = ref ($proto) || $proto;     # Make the Class Name
        my $parent= ref ($proto) && $proto;     # Get the Parent Class
+ (if Any)

        my $self = {};                          # Create the HASH for 
+the Object

        bless($self, $class);                   # Create the Object
        $self->{_PARENT}= $parent;
        $self->{_RESULT} = "";                  # Result of the method
+ call
        $self->{_STATUS} = 0;                   # Status Return (0 = O
+K)
        $self->{SERVER} = XXX->new();

       return $self;                           # Return the Object Ref
+erence
}

sub allowed_function
{
        my $self = shift;
        my $function = shift;
      
        if ($function eq "sane")
        {       
              return(1) ;
        }
        else
        { 
               return(0);
        }
}

sub AUTOLOAD
{
        my $self = shift;
        my $thing = $AUTOLOAD;
        $thing  =~ s/.*:://g;
        return if $AUTOLOAD =~ /DESTROY$/;
        if ($self->allowed_function($thing)
        {
                $self->{SERVER}->$AUTOLOAD(@_);
        }
}

If I have a method called 'sane', and one called 'insane' that is defined in the XXX module, I want to do the following 
my $X = XYZServer->new;
my $sane;

$sane = $X->sane;

[download]
I want the routine to execute, but if I say 

$sane = $X->insane;

[download]
I want it not to execute the routine !! I have been racking my brain oh how to do this, but it has me stumped.
