I'd recommend against using these in new code. I wrote them back around 2011 as a hack for something I was doing back then. Among the downsides of these is type information loss in both functions (since strings discard the information tag) and column order loss in toAA (since D associative arrays do not maintain any defined order). Additionally, they to make an additional copy of the result row, which you may be able to avoid by looping over it directly.
I may formally deprecate them in a future release.
