Summary: Evaluating keyPaths needs to be better specified

This bug is very similar to bug 9832, however since that bug is discussing a
lot of related issues, I wanted to file a separate one to make sure this isn't
forgotten.
Currently the syntax for parsing a keyPath isn't explicitly defined. It is
clear that for keypath/object
"foo.bar.baz"
{ foo: { bar: { baz: 4 } } }
the result is 4. However does keypath/object
"foo[1].bar"
{ foo: [ false, { bar: 4 }, true ] }
evaluate to 4? What about
"foo[x].bar"
{ foo: [ { bar: 4 } ], x: 0 }
or
""
4
Do either of those evaluate to 4? The last example could be useful when
out-of-line keys are used, but still wanting to be able to search on the stored
value.
