Indexer expressions like {{ myproperty[2] }} should work.

Of course you should also be able to nest an expression inside it like this {{ myproperty[ myotherproperty * 5 ] }}

Here is a test

I believe this is now fixed

I might be missing something, but it seems like this does not work in all cases : If you have an attribute like this one: objArray:[{name:"foo"},{name:"bar"}]

In a template , this works {{objArray.0.name}}

but this does not {{objArray[0].name}} (throws error : Invalid expression syntax: objArray[0].name)

I also whipped up a jsbin for clarity: http://jsbin.com/iFUlEBAp/2/edit?html,output
