How to traverse given slice env and check if multiple variables matches the given condition

[Dentrax]

I was struggling to create expressions for slices. I tried to write a bunch of expressions but couldn't able to end with a success compilation. What I want to do is:

• Given env is an []
• Enforce Name: E is existed in slice (any)
• If exists, must be Active: true (skip if it does not exist)

But I couldn't able to match E against a given Name field: any(#, {Name matches 'E'}) (tried both of . and #, fails with cannot use pointer accessor outside closure). Also tried Name in ['E'] but fails: invalid operation: int(string).

Here is an example snippet:

package main

import (
	"fmt"

	"github.com/antonmedv/expr"
)

type Inputs []Input

type Input struct {
	Name   string
	Active bool
}

func main() {
	inputs := []Input{
		{Name: "A", Active: true},
		{Name: "B", Active: false},
		{Name: "C", Active: true},
		{Name: "D", Active: false},
		{Name: "E", Active: true},
		{Name: "F", Active: false},
	}

	code := `WHAT HERE TO EVAL: Name = 'E' is exist and Active = 'true'?`

	program, err := expr.Compile(code, expr.Env(inputs))
	if err != nil {
		panic(err)
	}

	output, err := expr.Run(program, inputs)
	if err != nil {
		panic(err)
	}

	fmt.Println(output)
}

Can you please help me on this? Thanks!

Env can be only a struct or a map[string]any.
