--- Comment #13 from Frédéric Demians <frederic at tamil.fr> ---
For me, there is a design error in you dev. You send to TT a representation of
MARC record which is not correct. You loose the field order in the record, and
subfields order inside each field. The fields object sent to TT is a hashref of
arrayref of hashref of array. The valid representation is an arrayref (1 per
tag) of arrayref (1 per subfield) of arrayref (1 per pair letter/value).

So for example (bad example), if you have:

245 ## - TITLE STATEMENT
  a Title My first title
  b Remainder of title My remainder
  a Title My second title

With your represenation, you can't know anymore that the second $a comes after
$b. In MARC21, it's important since separators are in the subfield content
itself. Your 245 field will be represented like that:

  245 => {
    'a' => [
      'My first title',
      'My second title'
    ],
    'b' => [
      'My remainder'
    ]
  }
