initialised

Unions should require that all members are `= void` initialised.
Perhaps allow just one union member to omit the `= void` initialisation... but
zero would also be fine.
It's not possible that 2 or more members express initialisation intent, and it
should be a compile error.
struct S
{
union
{
int x;
float y; // COMPILE ERROR, 'x' already initialised!
}
union
{
int z;
float w = void; // <- this is fine
}
}
