Add Element to list not Working

[Chris Pons]

Thanks. I tried doing this and the list didn't update:

void AddToList( SList!int list, int i )
{
     list.insert( i );
}

SList!int intList;

AddToList( intList, 42 );

but when I switched to this, it worked:

SList!int intList;

void AddToList( int i )
{
     intList.insert( i );
}

AddToList( 42 );

The first method didn't give an error it just didn't update the 
list as I thought. Any idea?
