Damian Conway, in his book Perl Best Practices, considers it a better practice to use q{} (the single-quote operator with matching braces) instead of two single quotes because two single quotes is easily confused with a double quote for some font settings.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
