Consider the following minimal demonstration classes:

package Parent;
use Moose;

has 'knibbel' => (
    is => 'rw', 
    isa => 'HashRef[Maybe[Value]]',
    lazy_build => 1,
);
has 'knabbel' => (
    is => 'rw', 
    isa => 'ArrayRef[Maybe[Value]]',
    lazy_build => 1,
);

sub BUILD {
    my $self = shift;
    my $meta = $self->meta;
    print("BUILD called for " . __PACKAGE__ . "\n");
    no strict;
    foreach my $attribute ($meta->get_attribute_list) {
        print("Creating builder for attribute [$attribute]\n");
        *{__PACKAGE__ . '::_build_' . $attribute} = sub {
            my $self = shift;
            my $meta = $self->meta;
            my $fropsel = $meta->get_attribute($attribute);
            if ($fropsel->type_constraint->name =~ /^ArrayRef/) { retu
+rn []; }
            if ($fropsel->type_constraint->name =~ /^HashRef/) { retur
+n {}; }
        };
    }
    use strict;
}
1;

package Child;
use Moose;
extends 'Parent';

has 'knuisje' => (
    is => 'rw', 
    isa => 'Str',
    lazy_build => 1,
);

sub BUILD {
    my $self = shift;
    my $meta = $self->meta;
    print("BUILD called for " . __PACKAGE__ . "\n");
    no strict;
    foreach my $attribute ($meta->get_attribute_list) {
        print("Creating builder for attribute [$attribute]\n");
        *{__PACKAGE__ . '::_build_' . $attribute} = sub {
            my $self = shift;
            my $meta = $self->meta;
            my $fropsel = $meta->get_attribute($attribute);
            if ($fropsel->type_constraint->name =~ /^Str/) { return ""
+; }
        };
    }
    use strict;
}
1;

And this simple script to use it:

#!/usr/bin/perl -w
use strict;

use Parent;
use Child;

my $child = Child->new();
[download]

Which gives the following output:

$ ./testchild.pl
BUILD called for Parent
Creating builder for attribute [knuisje]
BUILD called for Child
Creating builder for attribute [knuisje]
[download]

Which is not quite what I expected, nor wanted :)
How can I avoid this issue, and access the attributes of the parent in the parent's BUILD-sub?
