Is the intent that these things preserve order? in which case, I like row
is OK (though still don't see what's wrong with record). I still dop'nt
love it though -- it gives the expectation of a row in a data table )or csv
file, or.. which will be a common use case, but really, it doesn't
conceptually have anything to do with tabular data.
in fact, one might want to store a bunch of these in, say, a 2D (or 3D)
array, then row would be pretty weird....
I don't much like entity either -- it is either way to generic -- everyting
is an entity! even less specific than "object". Or two specific (and
incorrect) in the lexicon of particular domains.
