I need to encode a key as string through json.
This throws an UTF-exception:
auto json = JSONValue(cast(char[])[0x00, 0x7D, 0xFE, 0xFF, 0x14,
0x32, 0x43, 0x10]);

Makes no sense. Either the bytes should be properly escaped or

The struct is very simple, it contains:
struct S {
SysTime a;
ulong b;
double c;
ubyte[] d;
string e;
}
And I tried:
bool foo(S[] params);
I have a DLL in D-code which returns an object and want to pass a
struct S[] to a member function of that object. The first element
is passed correctly, the rest is just garbage. In fact the next
item is just a single byte with value 0x11 following some 0x00.
It doesn't matter if I'm using S[]
