Made me think $fields = [$fields,@_] unless ref fields;

and not that it matters here, and i would have to look up funny debug commands to tell for sure, but are $#$fields-1 and $fields->[-1] optimized or does the subtraction happen every loop of $obj? Im never sure.

and in mine, besides $data,$fields,and $count as nicer variable names, i had already decided i should have $size1 be named as $nterminal and $size2 named as $nsubparts to make it clearer what they did. wasnt gun'a post as a "fix" but this gave me an excuse to mention it.

Edited to add: What about missing fields? $ref = $ref->{ $obj->{ $fields->[$_] // '.' } } //= {} where '.' is used like the SAS missing variable.
That wasnt right, instead $ref = $ref->{ $obj->{ $fields->[$_] } // '.'  } //= {}
