Is there any way of telling which side of the '=' a class []
operator is on?  I was thinking of a possible application in which
a disk file could be used as a virtual array.  A constructor could
be used to open the "virtual" array and a destructor would be used
to close the "virtual" array.  Using this scheme, object[] operations
appearing on the left hand side of the '=' would cause a write to the
associated file, and object[] appearing on the right hand side of the
'=' would cause a read of the disk array.

Thanks in advance,
James Card
