I think initializing structs should (almost) be always done with designated initializers, because otherwise it's easy to get the order wrong. The problem is that otherwise the order of fields gets additional meaning not only for the memory layout, but also for the code that initialize the structs. Add a macro NM_VARIANT_ATTRIBUTE_SPEC_DEFINE() that replaces the other (duplicate) macros. This macro also gets it right to mark the struct as const.
