Such behavior seems mislabeled if it is exposed as a _shallow_
branch capability.  It sounds to me more like a _lazy_ branch
capability.  My expection, based solely on connotation of the
term shallow, would be that once I request explicit construction
of such a beast its future peregrinations would be limited to my
prescribed horizon.
