Union member positions?
Is it possible to set a "position" on a union member? or is there is a language-integrated equivalent? For example, to get access to each byte in an unsigned integer while still supporting the original type. ```D ///a single uint that would be accessed as two ushort, or four separate ubyte union UnionExample{ uint EAX; //upper ushort EAHX; ubyte EAHH; ubyte EAHL; //lower ushort EALX; ubyte EALH; ubyte EALL; } ``` Thanks.

You can use anonymous `struct` and `union` blocks. ```D union UnionExample{ uint EAX; struct { //upper union { ushort EAHX; struct { ubyte EAHH; ubyte EAHL; } } //lower union { ushort EALX; struct { ubyte EALH; ubyte EALL; } } } } ```
