@observe was too complex. In practice, we only used @observe(after=) and almost exclusively called a single "sync properties to the DOM" method.
For now, we can safely refactor this functionality into @property via a change= attribute:
@property (change=_updateContent) title : String
Eventually, I'd like to have a simple observe attribute:
@property (observe) title : String
This would call propertyDidChange/observePropertyChange/etc in setTitle:. From there, implementation-specific methods like setNeedsUpdate or setNeedsLayout could be called.
