Re: Variadic functions and dynamic function calls

I'm now wondering if it makes more sense to have a way of programatically accessing the arguments as an array, like is done in languages like JavaScript. That is, defining a new function:
> 
>     fn:function-arguments($from as xs:integer := 1, $to as xs:integer? := ()) as array(*)
>     (: This function is ·deterministic·, ·context-dependent·, and ·focus-independent·. :)

Yes, I think this makes sense.

Note that we already have a function fn:apply() which supplies the arguments as an array. It's fairly useless in the absence of variadic functions, but could become much more useful in future.
