> It is a pain to reorder batches and guard behavior of certain batches /
> sequences of batches by a flag. This was primarily due to ample usage of
> `{{{}::`{}}}, `{{{}:::`{}}}, and {{`:+`}} to juggle rules and batches around
> which imposed syntactic limitations. For example, see here:

> We'd like to refactor to use unified logic.
