Hello! Is it possible to get a list of variables to evaluate formula? e.g.:
Formula:

$average([accuracy1, accuracy2])

I'd like to get a list:

[]string{"accuracy1", "accuracy2"}

It appears that the $eval doesn't work as expected.

Input

{
  "inputs" : [
	  {
		  "a" : 1,
		  "b" : "{\"c\":11}"
	  },
	  {
		  "a" : 2,
		  "b": "{\"c\":22}"
	  }
  ]
}

and the corresponding jsonata

$map(inputs,function($v){{
  "a": $v.a,
  "b": $v.b,
  "c": $eval($v.b).c
}})

should produce something like this

[
  {
    "a": 1,
    "b": "{\"c\":11}",
    "c": 11
  },
  {
    "a": 2,
    "b": "{\"c\":22}",
    "c": 22
  }
]

instead I am getting,

[
  {
    "a": 1,
    "b": "{\"c\":11}"
  },
  {
    "a": 2,
    "b": "{\"c\":22}"
  }
]

as you can see, "c" is silently failing

Hello, is it possible to add the $eval function as defined:

Thanks.

I'd like to evaluate formula:

$average([accuracy1, accuracy2])

Currently, If I don't set accuracy2, the library will ignore it and return value of accuracy1. Is it possible to mark some/all variables as obligatory?

Example:

expr, err  := jsonata.Compile("$average([accuracy1, accuracy2])")
if err != nil {
	log.Fatal("Invalid expression", err)
	return
}

res, err := expr.Eval(map[string]any{"accuracy1": 0.9}) 

Got result: 0.9, nil.
Wanted result: 0, errUndfinedVariable("accuracy2")
