Rules of good code (part IV)In this chapter IV.1 No "magic" values Timeouts, retries, sizes, limits, TTLs and thresholds are set once by a named constant or a config field and reused.
App. AThe grammar describes the syntax after lexical analysis (§1).
App. BWhen the draft was turned into the standard, contradictions were found and eliminated.
App. DThe list of all items of the Standard in which the behaviour is defined by the implementation or a feature is optional (§0.1).
Considerations for future revisionsThe items below are not part of the current edition and are not mandatory for implementations; this is material for discussion in the next revisions of the Standard.
