Re: [development] low hanging fruit for Drupal 6: variable defaults

- we can save extra typing and value passing on variable_get calls - we have a hook to reuse when we need a list of variables to present for localization

adds pluses over just using constants.

Sure, only using constants for default variable values could be make variable usage better, but I think a hook do more just by being a central place and not a set of unrelated constants.

i'd like to see this centralized in a hook too. we'll be one step closer to the hierarchy that adrian proposed long ago: http://lists.drupal.org/archives/development/2006-06/msg00309.html
