I'm wondering if this is related to a problem I'm seeing in this version
where a column listed in _inflated_column is undefined.

I've upgraded to SQL::Abstract 1.73 for both versions of DBIC below.

In 0.08196 I don't see the problem (I can't upgraded to .08197).

In 0.08198 what happens is I end up with a row with an _inflated_column
with the column undef.
In  0.08196 _inflated_column is a row object.

For example, if I'm modeling school work -- if a class has many
assignments, and an assignment has many papers, then:

my $paper =3D $schema->resultset( 'Paper' )->search(
    { 'me.id' =3D> $id },
        prefetch =3D> [
            { assignment =3D> 'class' },

my $assignment =3D $paper->assignment;
warn Dumper $assignment->{_inflated_column};

print $assignment->class->id;

# in .08198 $assignment->{_inflated_column}{class} is undefined
# in .08196 $assignment->{_inflated_column}{class} is a class row object.

Which results in:

$VAR1 =3D {
          'class' =3D> undef
Can't call method "id" on an undefined value ....

If I revert to 96 then "class" references a ::Result::Class object.

Is this a know issue?
