NAME
       KiokuDB::Role::Immutable - A role for objects that are never updated.

SYNOPSIS
	   with qw(KiokuDB::Role::Immutable);

DESCRIPTION
       This is a role for objects that are never updated after they are inserted to the database.

       The object will be skipped entirely on all update/store operations unless it is being collapsed for the first time, and its child objects
       will not be updated unless they are found while collapsing another object.

       This means that:

	   my $immutable = $kiokudb->lookup($id);

	   $immutable->child->name("foo");

	   $kiokudb->update($immutable);

       will not work, you need to update the child directly:

	   $kiokudb->update($immutable->child);
