HMP command arguments are specified by an args_type string, which can't express "enumeration", so we use strings instead. We could hack in another arguments type 'E', abusing the parameter name like type 'O'. But I think the args_type string is long past its "best before" date. We could replace it by a command schema, like QMP's. Differences to QMP include: arguments are positional, fewer types are accepted, and there's convenience syntax such as size suffixes. Not exactly an easy task, I'm afraid. [...]
