You missed the part about it having a default_ctor. Use of -default_ctor or -default changes the behavior of *_isset(). I'm not arguing the design decision, but I want to be able to turn off the optimization.

Here's a testcase to demonstrate what I'm talking about. 

use strict;

use Test::More 'no_plan';

package Bar;

sub new { bless {} }

package Foo;

use Class::MethodMaker [
    new => 'new',
    scalar => [
        { -type => 'Bar', -default_ctor => 'new' }, 'bar',
    ],
];

package main;

my $foo = Foo->new;
isa_ok( $foo, 'Foo' );

my $bar = $foo->bar;
isa_ok( $bar, 'Bar' );

$foo->bar_reset;
ok(
    !$foo->bar_isset,
    "No get() after reset(), so why is it set()?"
);
-----------------
ok 1 - The object isa Foo
ok 2 - The object isa Bar
not ok 3 - No get() after reset(), so why is it set()?
1..3

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
