FWIW, I tend to handle this problem the same way I handle other DRY
problems with magic constants: give the default value a name and
either export it directly, or export an API for retrieving it.
If that results in name sprawl ("But now I have 15 defaults to
export!"), then I take it as a hint that I may not be modeling my data
correctly, and am missing a class definition or two somewhere.
Cheers,
Nick.
