This may be, but it is not documented as such, and it breaks any attempt to
iterate over the returned hash (without special treatment).
Since I need to iterate over all values for all rows, I am now facing a choice:
1- Either I iterate using [an array of] hashes, testing each key as I go
2- Or I iterate in the default mode of [an array of] arrays, with no test, as
each value is present once and only once.
Without the test, option 1 was more attractive as the iterative treatment
consists of outputting all records one line per column name, followed by one
line per corresponding value.
With the test, Option 2 becomes equally attractive, and (I suspect), more
efficient.
Comments welcome.
