[MacRuby-devel] Using Virtus or SmartProperty as outlets?

Sorry - I didn't make that clear! 

You're right, Stephen: I'd like to Virtus' "attribute" or SmartProperty's "property" *instead* of attr_accessor. I can roll my own solution, but I'd like to not have to! (Besides laziness, and the strong possibility of introducing bugs into any solution I come up with, I really like the strong validations and coercions of Virtus - and it's useful for database entries. And it's already written and mostly debugged.)

I'd like to use something like SmartProperties (for lightweight situations) or Virtus (when I absolutely must have industrial-strength validations, etc) as outlets. My experiments, such as they are, aren't helping me any! What, if anything, am I doing wrong?

But sometimes I'd like the "defaults" capability of Virtus & SmartProperty, and I'd definitely like the industrial-strength validations of Virtus when I'm working against the database.
