Yeah I already encountered that problem. That's why I had to 
cast(ubyte[]) it (where conversion is expected) for my reinterpret casting:

RGB[] PALETTE = (cast(RGB*) cast(ubyte[]) [...])[0..256];

You're right. But it only concerns casting to a struct(?) or an array of 
structs, right?!. Conversion is correct for standard arrays, but struct 
arrays need to be reinterpret cast (correct me if I'm wrong, I can't 
imagine how conversion could be reasonably used. Only thing might be 
casting an array of structs to another array of structs but I don't know 
any valid use-case).
