- Encourage single line nested namespace declarations.
- Reference and allow `constinit` in the relevant sections
- Update operator overloading guidance for comparison operators: prefer
only to overload `==` and optionally `<=>` when there is an obvious
ordering, and allow the compiler to derive the other comparison
operators.
- Discourage prefixing `uint32_t`, et cetera with `std::`.
- Document when and how to use concepts:
- Use `requires` expressions rather than the alternatives, e.g. a
template parameter.
- Do not reimplement existing concepts/traits.
- Do not expose concepts across API boundaries.
- Do not use concepts unnecessarily.
- Do not implement concepts that are not compile-time checkable.
- Update caveats for `thread_local` usage, particularly around the risk
of destruction order issues.
- Provide explicit guidance for situations where `bit_cast` may be a
better fit than `reinterpret_cast`.
- Emphasize that kConstant-style naming can still be used for `const`
automatic variables that are initialized at runtime, but only if the
resulting variable has the same value with each evaluation (i.e. it
does not depend on runtime inputs).
- Clarify what sorts of details belong in file-level comments vs
comments for individual abstractions.
- Update TODO examples to reflect the preferred styling, from most
preferred to least preferred.
This relaxes the guidance around indenting by 4 additional spaces and provides the Prettier format as one of the examples to ensure the style guide is compatible with the Prettier formatter.
- Encourage use of the `internal` namespace to document parts of an API
that are not public.
- Create a separate section for `switch` statements.
- Require a project-specific prefix for macros.
- Reorganize guidance for formatting conditional statements.
- Other miscellaneous wording and formatting fixes.

Suggestion works out.
There is no Common Lisp operator named PRINT-UNPRINTABLE-OBJECT. Given the context, it is certain that PRINT-UNREADABLE-OBJECT (www.lispworks.com/documentation/lw51/CLHS/Body/m_pr_unr.htm) was meant instead.
- Include friend types in class declaration order guidance.
- Include previously omitted text (due to mismatched tags) about
preferring int16_t over short, et cetera.
- Function declarations:
- Updated guidance for what comments should cover.
- Add a C++ attribute example.
