           Summary: Immutable union instantiations too
           Product: D
           Version: D2
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Keywords: rejects-valid
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody at puremagic.com

struct Foo1 {
    ushort bar2;
}
struct Foo2 {
    union  {
        ubyte[2] bar1;
        ushort bar2;
    }
}
void main() {
    immutable Foo1 foo1 = { bar2: 100 }; // OK
    immutable Foo2 foo2 = { bar2: 100 }; // error
}



DMD 2.059 gives:

test.d(12): Error: variable test.main.foo2 is not a static and cannot have
static initializer


(Maybe it's just a well known problem of unions not supported in CTFE?)
