I'm not sure what you mean.  Here's a less abbreviated example:

use Template;
use Template::Stash;
use strict;

package Object;

sub new {
  my ($class, $addend) = @_;
  bless { addend => $addend }, $class;
}

sub field {
  my ($self, $arg) = @_;
  return $arg + $self->{addend};
}

package main;

$Template::Stash::HASH_OPS->{dofield} = sub {
  my ($fielder, $num) = @_;
  return $fielder->field($num + 2);
};

my $obj = Object->new(1);
my $t = Template->new;

$t->process(\'[% obj.dofield(3) %]', { obj => $obj })
  or die $t->error;


This prints "6", showing that the hash vmethod "dofield" has dispatched to
the "field" method of $obj.
