       Tangram::Type::Dump::Perl - map any Perl object as scalar dump


          use Tangram::Core;
          use Tangram::Type::Dump::Perl; # always

          $schema = Tangram::Schema->new(
             classes => { NaturalPerson => { fields => {

             perl_dump =>
                diary => # diary is a perl hash
                   col => 'diarydata',
                   sql => 'TEXT',
                   indent => 0,
                   terse => 1,
                   purity => 0

                lucky_numbers => 'int', # use defaults


       Maps arbitrary Perl data structures by serializing to a string representation. The
       persistent fields are grouped in a hash under the "perl_dump" key in the field hash.

       Serialization is done by Data::Dumper, which traverses the Perl data structure and creates
       a string representation of it. The resulting string will be mapped to the DBMS as a scalar
       value. During restore, the scalar value will be eval'd to reconstruct the original data

       As of Tangram 2.07.1, persistent references are safely handled via the Tangram::Type::Dump
       utility class.

       The field names are passed in a hash that associates a field name with a field descriptor.
       The field descriptor may be either a hash or a string. The hash uses the following fields:

       ·   col

       ·   sql

       ·   indent

       ·   terse

       ·   purity

       The optional fields "col" and "sql" specify the column name and the column type for the
       scalar value in the database. If not present, "col" defaults to the field name and "sql"
       defaults to VARCHAR(255).  Values will be always quoted as they are passed to the

       The remaining optional fields control the serialization process. They will be passed down
       to Data::Dumper as values to the corresponding Data::Dumper options. The default settings
       are: no indentation ("indent=0"), compact format ("terse=1"), and quick dump ("purity=0").
