I see. Looking at this on Sunday I see in assignment nodes fpc_copy_proc would
need to be modified or a new fpc_move_proc introduced which (for now at least)
would only affect records which had a move operator. In theory the concept
could be extended to dynamic arrays and other reference counted types but
that’s another story.
