Since 0.3.0 binding array elements doesen't work

[arodic]

With 0.2.4 you used to be able to bind {{value[0]}} or this.$.element.bindProperty('value', new PathObserver(this.value, 0)); Since 0.3.0 that does not appear to work.

Can you give some more detail? Binding to array elements seems work correctly in 0.3.1:

It correctly renders the value at array[0], and observes the change when you click on the element.
If you're still seeing this, please provide a code sample that reproduces the bug.

True, it seems to work correctly with mustache binding. However, bindProperty seems to fail. Here is a jsbin: http://jsbin.com/vuragono/5/edit

Expected result is Hello, Bob! as with 0.2.4.

Ah, yes. Sorry, this probably needs to be doc'd. The path '0' is now a syntax error. The correct syntax is '[0]'. The idea here is that paths are as if they followed a JS identifier and support member expressions with constants and property expressions.
