Accessing arguments in variadic functions

[deepilla]

JSONata allows you to define functions that accept a variable number of arguments. But I can't work out how to access those arguments from within a lambda function. Perhaps this is only possible in JavaScript extensions.

Let's say I need a function that takes one or more numeric arguments and returns the total. What do I put in the function body to make the expression below return 6?

(
    $f := function($x)<n+:n>{ ... };
    $f(1, 2, 3)
)

You're right, this is only possible in extension functions. I'll flag this as an enhancement request.
Thanks!
