NOTE FOR COLUMN NAME METHOD

Teng::Row has methods that have name from column name. For example, if a table has column named 'foo', Teng::Row instance of it has method 'foo'.

This method has different behave for setter or getter as following:

    # (getter) is alias of $row->get('foo')
    # so this method returns inflated value.
    my $inflated_value = $row->foo;

    # (setter) is alias of $row->set_column('foo', $raw_value)
    # so this method does not deflate the value. This only accepts raw value but inflated object.
    $row->foo($raw_value);

This behave is from historical reason. You should use column name methods with great caution, if you want to use this.
