NOT.2:8 - Common Anti-Patterns and How to Avoid Them

Failure	Repair
Supplying a constructor list without binding rules	State which constructors introduce names and where those names apply. The sum’s index declaration governs its body.
Treating a repeated spelling as the same reference	Resolve the occurrence through its context. Local `p` can hide the external parameter in the sum example.
Checking input types but ignoring operand roles	Identify ordered or named places. The ratio receives numbers in either arrangement but computes different answers.
Letting layout imply an undocumented operation	Define which spatial or temporal relations carry grouping and connection; preserve those relations when changing presentation.
Dropping delimiters without recoverability or equivalence	Retain them until the precedence rule or an appropriate equivalence justifies their omission.
