For those working on dcop related things, 

I extended DCOPidl to support "k_dcop" sections without explicitely named
identifiers. You can name your arguments, but you don't have to. Furthermore,
there's a new magic return value ASYNC.

Example:
...
   K_DCOP
...
k_dcop:
    void append( const QString& );
.....


makes append() a synchronous call that returns void. Slower, but has the
advantage that users calling the function from generated stubs can use
DCOPStub::status() to check whether the call succeeded.

An assynchronous call (corresponds to DCOPClient::send() ) can be done with 

...
   K_DCOP
...
k_dcop:
    ASYNC append( const QString& text );
.....

The skeleton is no different (ASYNC expands to void), but the stubs will use
send() instead of call().

You may check your interfaces, I assume there are many places were a call
can be done better and faster with ASYNC than with void.
