[xquery-talk] xquery 3.1 wishlist

[Michael Kay]

I would think both of these could be implemented as user-defined functions but it’s hard to know without seeing a specification: saying you want a function called array:index-of() is not very informative unless you explain exactly what you want the function to do.

If it’s to behave like fn:index-of() then you can write it as

array:index-of($array, $value) {
   (1 to array:size($array))[ $array(.) = $value ]
}

which is hardly a great hardship to write as a user-defined function.
