There is no mention of computed properties in the docs, should we use getter for that ? It seems to work: http://jsbin.com/vihawiziza/edit?html,css,js,output
I really like getters/setters or proxy interfaces for data handling, it has several benefits regarding autocompletion, type checking and the handling of specific mutations like array splice. This is what sold me with Vue in the first place
Yeah, the docs don't mention a couple things (yet). Check out http://jsbin.com/sosunuvuwi/edit?html,css,js,output for an example on computed properties.
The getters/setters added have an overhead and slow down the startup time of an application. I'm working on a simple plugin that can add them though, along with the array methods :)
