Re: Undocumented array_val[generate_series(...)] functionality?

One can indeed infer that if the expression chosen for subscript is an SRF that the resultant output will also be an SRF.  It seems less than helpful to force the reader to infer that, IMO.  Especially when the slice syntax, which could conceivably return either a sub-array OR a set, the later being the undocumented reality (our function examples document the actual outputs, these examples probably should do the same.  I would be OK if we simply added an SRF example and showed the SRF result it produces without changing the wording - though this doesn't seem like a hard improvement to make.  I'll offer something up if a committer at least agrees it could use some work).
