Compound assignment operators

[Yao G.]

Is there a way to make compound assignment operators (-=, +=, *= and  
friends) work with D's operator overload regime? I can't make them work.

> struct Foo
> {
>     this( int foo )
>     Foo opBinary(string op)( in typeof(this) rhv )
>     if( op == "-=" )
>     {
>          _bar -= rhv._bar;
>          return this;
>     }
>
>     private int _bar;
> }
>
> void main()
> {
>     au
