Thanks, that looks like exactly what I need. I wonder if someone could
put a reference to this array utility package in the manual, chapter 8, on
arrays.

Maybe something like this:
For more complex work with arrays, see Massimo Dal Zotto's contrib package
'array_iterator'. This loadable module "...defines a new class of
functions which take an array and a scalar value, iterate a scalar
operator over the elements of the array and the value, and compute a
result as the logical OR or AND of the iteration results."
