           Summary: Accessing immutable AA in  nogc with index results in

It will throw the following compilation error


  Error: indexing an associative array in ` nogc` function `app.myfunc` may
cause
  a GC allocation


Here is a code example:


  immutable int[int] aa;

  shared static this () 
  {
        aa[10] = 20;
        aa[20] = 30;
  }

  int myfunc ()  nogc
  {
        return aa[10];
  }
