           Summary: anonymous enum without {} doesn't work as asm value

The anonymous enum syntax allows the {} to be omitted if there is only one
value, as described under "Manifest Constants" in the spec. However, they seem
to behave differently to single value anonymous enums that do have braces when
used as immediate values in the inline assembler. Test case...

import std.string;

enum n1 = 42;
enum { n2 = 42 }

uint retN1() {
    asm {
        mov EAX,n1; // No! - mov EAX,-4[EBP]
    }
}

uint retN2() {
    asm {
        mov EAX,n2; // OK - mov EAX,02Ah
    }
}

unittest {
    assert( retN1() == 42, "expected 42, got "~toString( retN1() ) );
    assert( retN2() == 42, "expected 42, got "~toString( retN2() ) );
}

void main() {}
