I can see the argument against using Singletons just as global variables.

But in many circumstances they are useful. The most obvious two situations I use them are in:

Passing a database handle to all methods, or to multiple objects gets sloppy fast - but having a single resource to fetch it from is neat.

Similarly with debug files; although they are sometimes abused when you realise you need more than one logfile...

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • 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.
  • Please read these before you post! —
