=head1 NAME
Mail::Message::Field::Flex - one line of a message header
=head1 INHERITANCE
Mail::Message::Field::Flex
is a Mail::Message::Field
is a Mail::Reporter
=head1 SYNOPSIS
=head1 DESCRIPTION
This is the flexible implementation of a field: it can easily be
extended because it stores its data in a hash and the constructor
(C<new>) and initializer (C<init>) are split. However, you pay the
price in performance. L<Mail::Message::Field::Fast|Mail::Message::Field::Fast> is faster (as the
name predicts).

=over 4
If you stick to this flexible class of header fields, you have a bit
more facilities than with L<Mail::Message::Field::Fast|Mail::Message::Field::Fast>. Amongst it, you
can specify options with the creation. Possible arguments:
=over 4
=item * B<new> LINE
ass a LINE as it could be found in a file: a (possibly folded) line
which is terminated by a new-line.
=item * B<new> NAME, (BODY|OBJECTS), [ATTRIBUTES], OPTIONS
A set of values which shape the line.
=back
To be able to distinguish the different parameters, you will have
to specify the OPTIONS as ARRAY of option pairs, or HASH of options.
The ATTRIBUTES are a flat list of key-value pairs. The body is
specified as one BODY string, one OBJECT, or a reference to an array
of OBJECTS. See L<Mail::Message::Field|Mail::Message::Field>:
Option --Defined in --Default
attributes []
comment undef
log Mail::Reporter 'WARNINGS'
trace Mail::Reporter 'WARNINGS'
. attributes => ATTRS
=over 4
Reference to array with list of key-value pairs representing attributes,
or reference to a hash containing these pairs. This is an alternative
notation for specifying ATTRIBUTES directly as method arguments.
=back
. comment => STRING
=over 4
A pre-formatted list of attributes.

=head1 DETAILS
=head1 DIAGNOSTICS
Warning: Field content is not numerical: $content
=over 4
The numeric value of a field is requested (for instance the C<Lines> or
C<Content-Length> fields should be numerical), however the data contains
weird characters.
=back
Warning: Illegal character in field name $name
=over 4
A new field is being created which does contain characters not permitted
by the RFCs. Using this field in messages may break other e-mail clients
or transfer agents, and therefore mutulate or extinguish your message.
=back
Error: Package $package does not implement $method.
=over 4
Fatal error: the specific package (or one of its superclasses) does not
implement this method where it should. This message means that some other
related classes do implement this method however the class at hand does
not. Probably you should investigate this and probably inform the author
of the package.
