Hi Francois,
the reason for it was that it doesn't make sense to have a single union with a
flexible array element, for example:
union A {
int a;
char[] b;
};
but I definitely agree that having them in unions is OK as long as they're
nested inside another struct (and all fields are flexible array members etc).
