--- Comment #1 from Zach the Mystic <reachzach at gmail.com> ---
I tested it and this works:

// change this:
// value = -(cast(T)-header);

// to this:
value = cast(T)cast(byte)header;

header is a ubyte. When changed to a byte, in this context, it becomes
negative. The compiler then creates a corresponding negative int.
