  Target Milestone: ---

People are frequently asking us how to iterate through array entries. A future
helper function "array:members" would be convenient, which wraps each array
member into a new array:

Example query:

  (: Current representation in XQuery :)
  declare function array:members(
    $array as array(*)
  ) as array(*)* {
    for $i in 1 to array:size($array)
    return [ $array($i) ]

  let $array := [ 1 to 2, 3, () ]
  for $member in array:members($array)
  return <hit>{ $member }</hit>


  <hit>1 2</hit>

A similar function could be provided for map entries.
