Caller is getting a modifiabled reference to the datum (otherwise they would use "get"): assume that it will be used to modify the datum and mark it as dirty.

Set operations to a rekeyable VB are allowed to change the shapes of the values. When T derives from casacore::Array, the assign method will use casacore::Array::assign which resizes the destination value to match the source value. For nonkeyable VBs, the normal operator= method is used which for Arrays will throw an exception when a shape incompatibility exists between the source and destination.
