- *Rationale*: Ensure determinism by avoiding accidental use of uninitialized
values. Also, static analyzers balk about this.
- By default, declare single-argument constructors `explicit`.
- *Rationale*: This is a precaution to avoid unintended conversions that might
arise when single-argument constructors are used as implicit conversion
functions.
- Use explicitly signed or unsigned `char`s, or even better `uint8_t` and
`int8_t`. Do not use bare `char` unless it is to pass to a third-party API.
This type can be signed or unsigned depending on the architecture, which can
