- *Rationale*: Behavior is undefined. In C++ parlor this means "may reformat

- Watch out for vector out-of-bounds exceptions. `&vch[0]` is illegal for an
empty vector, `&vch[vch.size()]` is always illegal. Use `begin_ptr(vch)` and
`end_ptr(vch)` to get the begin and end pointer instead (defined in
`serialize.h`)
- Watch out for out-of-bounds vector access. `&vch[vch.size()]` is illegal,
including `&vch[0]` for an empty vector. Use `vch.data()` and `vch.data() +
vch.size()` instead.
- Vector bounds checking is only enabled in debug mode. Do not rely on it
