You could emulate this with a variant record containing a vector element, but a modifier or directive would be of course be more convenient (and easier to implement). To avoid having to add alignment information to all symbols, I would limit this functionality to recorddefs and objectdefs though (there we already keep track of the alignment requirements via the tabstractrecordsymtable(symtable).recordalignment field).
