Hi,
a more general question would be the following. I got the impression that
RemoteArray is something like an inherited class from Array with the extra
information home() that points to the place where the RemoteArray lives.
That would mean that all methods from Array carry over to RemoteArray.
Is this impression correct ? Or in parts correct ?
