Also, not sure I understand the \texttt{_BitInt(N)} types are byte-aligned to the next greatest power-of-2 = up to 64 bits. sentence because for N <=3D 64 there are different rules that apply (size a= nd alignment same as smallest standard integral type that can contain them) and so IMHO = it should just say that the N > 64 bit-precise types are 64-bit aligned.=
