Accessing array elements doesn't work within an expression using ExpressionSyntax

[sorvell]

This works:

{{ someArray.0 }}

Accessing array items is convenient (e.g. I want to display the first video in a prioritized list of video data).

Accessing an array element within an expression does not work:

{{ someArray.length > 0 ? someArray.1 : 'none' }}

Here's an example: http://jsbin.com/agacet/1/edit

I wonder if the bracket syntax works?

{{ someArray.length > 0 ? someArray[1] : 'none' }}

That seems a little more intuitive, IMHO.
