* Another use-case: When inserting a key into a map, {{Code|$f}} decides how to combine the new value with a possibly existing old one. {{Code|hof:const}} here means ignoring the old value, so that's normal insertion.
<syntaxhighlight lang="xquery">
$ins($map, 'foo', 42)('foo')
)
</syntaxhighlightpre>
returns {{Code|3 42}}
|}
