Bug? when calling once() multiple times directly after each other

[joshbenham]

Hey not sure if this is a bug or just an oddity...

Basically what I originally had was

$year = once(fn () => Year::where('value', $row['year_value'])->first());
$model = once(fn () => Model::where('name', $row['model_name'])->where('year_id', $year->id)->first());
$colour_code = once(fn () => ColourCode::where('code', $row['colour_code'])->first());

And the weird thing is that $model and $colour_code were returning the results of $year. Not sure if it was to do with the Stack Trace and maybe the code was too close together.

So I changed it to instead using functions like

$year = $this->getYear($row);
$model = $this->getModel($row, $year);
$colour_code = $this->getColourCode($row);

And in those functions just extracted the once code out

    private function getYear($row): Year
    {
        return once(fn () => Year::where('value', $row['year_value'])->first());
    }

    private function getModel($row, $year): Model
    {
        return once(fn () => Model::where('name', $row['model_name'])->where('year_id', $year->id)->first());
    }

    private function getColourCode($row): ColourCode
    {
        return once(fn () => ColourCode::where('code', $row['colour_code'])->first());
    }

And it worked perfectly.

No issues on my side not that its working was more just curious if it was a bug or a pitfall of using the stack trace.
