We have looked at this in the past, and the problem is what kind of thing a function such as map:entries() might return. There was a proposal on the table to introduce tuples, but it was too complex. One possibility is to return a map with two entries named "key" and "value".To get all values from a map as a single sequence I write for $k in map:keys($mymap) return $mymap($k) which is long and also probably ineffective (O(NlogN)?) If brevity is the concern, you can do map:keys!$mymap(.) (But in practice I suspect wanting all the values is rare; people will usually want the keys as well, except perhaps in the case where the key can be computed as a function of the value). Incidentally, we've never had any kind of capability to iterate over / enumerate the values of a key(). Michael Kay Saxonica
