Behaviors are inherently an implementation detail, and you should not be exposing them directly to users of your type. Instead, you should expose just the operations you expect to be needed through your own calls, which you can reimplement as needed.
I'm leaning in this direction too. The idea of exposing the behavior itself as a value seems wrong for almost any client. "foo.prop.reset()" is slightly nicer than "foo.resetProp()", but not if it conflicts with a 'reset' that's already on the property type. "foo.prop at behavior.reset()" certainly isn't an improvement.
