How do I pass an object to another script?

It's been a while (a few years, actually) since I picked up Unity and I'm trying to get back into it. From what I've seen so far, #pragma strict appears to be all the rage lately. However, it apparently doesn't use dynamic typing, which I think is the root of my issue. I'm simply trying to pass an instance of a class from one script to another. However, I'm getting this error:

'name' is not a member of 'Object'

When I attempt to run this code:

In Item.js:

 function OnTriggerEnter(other : Collider) {
     if(other.gameObject.CompareTag("Player")) {
         var weapon = new PlayerItem("Test Weapon Name");
         other.SendMessage("AddItemToInventory", weapon);
     }
 }

In PlayerInventory.js:

 class PlayerItem {
     var name : String;
     function PlayerItem(g_name : String) {
         name = g_name;
     }
 }
 
 function AddItemToInventory(itemProperties) {
     Debug.Log(itemProperties.name);
 }

Where did I go wrong? UnityScript today isn't the UnityScript I remember. Heh.
