of pointers to cpu structs, rather than an array of structs themselves.
Implementing this is trickier as one may not know what to allocate until
one has parsed the args. Parsing the args twice wouldn't be unreasonable,
IMHO. If the state struct ever does contain an array of pointers then we
can't do this here. */
