cómo cargar cada elemento del objeto de la matriz con la palabra clave `this`

Tengo una matriz algo como esto:

 let arr = [ { num: 10, reload: () => { this.num = 30; } }, { num: 40, reload: () => { this.num = 20; } } ]

entonces estoy tratando de ejecutar este código

 arr.forEach(item => { item.reload() })

Quiero que el primer objeto de la matriz tenga num = 30 y el segundo como num = 20

this no parece funcionar ...
