Bug#772737: /usr/share/perl5/Mail/Message/Field.pm: Warning for possible typo when using warnings/strict

[Herwin Weststrate]

Package: libmail-box-perl
Version: 2.117-1
Severity: minor
File: /usr/share/perl5/Mail/Message/Field.pm
Tags: patch

$ perl -cw /usr/share/perl5/Mail/Message/Field.pm
Name "Mail::Message::Field::size" used only once: possible typo at /usr/share/perl5/Mail/Message/Field.pm line 102.
/usr/share/perl5/Mail/Message/Field.pm syntax OK

Even though it doesn't break anything, it's ugly. Possibilities for fixes:

- Rewrite it to a sub (will be slower in theory)
- Define a call somewhere to size, so it is used again. For example, add
  the following to the line below:
 
  { my $sub = sub{ size(); }; }

  The anonymous sub goes directly out of scope, so this doesn't clutter
  the namespace.
