Summary: compiler failure, table2[key] = 

Initial Comment:
Sorry wasn&#039;t obvious how to make this smaller

Nice compiler version 0.9.8 prerelease (build 2004.03.25, 
17:17:17 UTC)

void main(String[] args){
   var n = 1;
   let nKeys = 10000;

   let table1 = new HashMap(nKeys);
   let table2 = new HashMap();
   for (int i = 0; i <= nKeys; i++) 
      table1["foo_" + i] = new Cell(value: i);

   String key;
   int v1;        
   ?Cell c2;   

   while (n-- > 0) 
     for (each : table1.entrySet) {
         key = each.getKey;
         v1 = each.getValue.value;   
                    
         if ( (c2 = table2[key]) != null)
            c2.value += v1;   
         else 
            table2[key] = new Cell(value: v1); //HERE
      }   
}

class Cell { int value; }
toString(Cell c) = c.value.toString;
