You might also use UNIVERSAL::can(), which might make the OO interface slightly more regular: 

c:\@Work\Perl\monks>perl -wMstrict -le
"print qq{perl version: $] \n};
 ;;
 use constant {
   STUFF => {
     'bizz' => 'foe',
     'bazz' => 'fie',
     'bozz' => 'fee',
     'buzz' => 'wiz',
     },
   };
 ;;
 my $obj = Kid->new;
 ;;
 my $n = 0;
 ;;
 METAMETHOD:
 for my $meta_method (qw/bizz buzz bazz zotz bozz/) {
   if (not exists STUFF->{$meta_method}) {
     print qq{no method corresponds to '$meta_method'};
     next METAMETHOD;
     }
   ;;
   my $method = STUFF->{$meta_method};
   ;;
   my $coderef = $obj->can($method);
   if (not $coderef) {
     print qq{cannot '$meta_method'->'$method' on }, ref $obj;
     next METAMETHOD;
     }
   $coderef->($obj, $method, $n++);
   }
 ;;
 { package Dad;
   ;;
   sub new { my $class = shift;  return bless \my $x => $class; }
   sub fee { my $self = shift;  $self->all(@_); }
   sub all { my $self = shift;  print qq{method '$_[0]', n == $n}; }
   }
 ;;
 { package Kid;
   ;;
   use parent -norequire, qw(Dad);
   sub new { my $class = shift;  return $class->SUPER::new; }
   sub fie { my $self = shift;  $self->all(@_); }
   sub foe { my $self = shift;  $self->all(@_); }
   }
