--- Comment #1 from Manfred Nowak <svv1999 at hotmail.com> ---
Specs.20.8|1 require `opIndex` to be a method. Therefore this is not a bug, but
an enhancement.

Although that requirement can be satisfied by declaring

  class C{
    bool delegate( int) opIndexVar;
    bool opIndex( int arg){
      return opIndexVar( arg);

the result would be an additional call unless the machine code generator
optimizes that call away.
