@aeschli, I am not 100% certain of this change. On line 828 there is if (scope.length < identifers.length) { which seems to indicate that it's ok for the scope array to be longer than the identifiers array. However, without my change, the condition on 838 is hit and -1 is returned if the scope array is longer than identifiers.
