The feature does not available in Rhino by default as it violates 
ECMAScript standard. You have to subclass Context to override 
Context.hasFeature(int featureIndex) to return true when featureIndex is 
Context.FEATURE_MEMBER_EXPR_AS_FUNCTION_NAME.

You may also return true instead of calling super.hasFeature for 
Context.FEATURE_NON_ECMA_GET_YEAR to emulate JScript in this particular 
case as well.

AFAIK in MSIE you can use either foo[bar] or foo(bar) for all collection 
objects.
