Description

The current next-item evaluation only supports evaluation of the last item in a sequence. For example, given sequence a b c d, the inputs are a b c and the output is d.

We expect to support evaluating every next-item in test sequence. For example, given sequence a b c d, the outputs are b, c, d with the respecting inputs are a, a b, and a b c.
