Hi Marc, This was a deliberate restriction: As maps and arrays are function items, and as they can contain references to other functions that have been declared in the evaluated query, it is generally tricky to evaluate and return them dynamically.
However, I spent some more thoughts on the underlying semantics, and I may have found a solution that overcomes some of the earlier limitations. A new snapshot is available [1], which now allows you to return function items (incl. maps and arrays) as result of xquery:eval. Your testing feedback will be welcome.
