           Summary: Getting all vales from a map

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)?)

I propose to add a function 

which would return all values from a map as a sequence. Unlike the code above,
it could be implemented in O(N). 

Also, when I have a map entry (a map containing one item) in variable $entry,
I can write map:keys($entry) to get the key of the entry. 
To get the value, I must write 
$entry(map:keys($entry)), which is a bit convoluted and could be replaced by
