[tpm] hash naming convention: singular or plural

[Alexander Anderson]

Hello Toronto Perl Mongers,

Names of scalars are usually singular, for example,

  $month = 'Aug';

Names of arrays are usually plural, for example,

  @months = qw(Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec);

How do you name your hashes, for example,

  %months = ( Jan => 1, Feb => 2, ..., Dec => 12 );
  or
  %month = ( Jan => 1, Feb => 2, ..., Dec => 12 );

Thanks.
