Howabout reusing 'overriding'? (Assuming record A w/ components B, C, & D.)

A := (Overriding B, C => <>, D = A.D);

I'd assume that 'overriding' should be given to *every* replaced 
component and "<>" or "RECORD.COMPONENT" for old [unchanged] values. 
(Though, we'd have to decide whether '<>' meant "keep things the same" 
or "use the component's default [or type's if not available, 
compiler-error if no default]")
