I'm in the middle of designing support for serializing singletons with Storable in Class::InsideOut -- which will be the last feature before 1.0.

I could benefit greatly by hearing some examples and opinions for any or all of these questions:

  1. How do you use singleton objects currently?
  2. Do you serialize them? If so, how?
  3. When thawing, if no singleton has yet been created, how do you regenerate the singleton from frozen values?
  4. If a thawed singleton "conflicts" with an existing singleton, how do you resolve that conflict?

References to specific modules or applications where I could see code would be very useful, too.

For those who don't understand why serializing singletons is a tricky proposition with Storable, it revolves around the necessary limitations of the STORABLE_attach hook. Here are a few references about it here and on RT:

Advice and insights on this topic would be greatly appreciated.
