15 * FIXME: Acessing the desc_struct through its fields is more elegant,
16 * and should be the one valid thing to do. However, a lot of open code
17 * still touches the a and b acessors, and doing this allow us to do it
18 * incrementally. We keep the signature as a struct, rather than an union,
19 * so we can get rid of it transparently in the future -- glommer
