C.29.2:9 - Consequences

The practitioner can now tell whether the computation answers the question, answers a useful restricted question, or still lacks a particular construction. Procedure recovery can expose missing information before implementation, and a representation-level estimate can reject an infeasible design before substantial resource use.

The cost is making the answer-producing connection explicit. For an ordinary small calculation this may take only a few lines. A large or delicate problem can require substantial algorithmic and numerical work; this pattern helps identify that work and connect its results, but does not remove it. Retaining a simple reference procedure may cost extra implementation effort while providing an intelligible comparison for an optimized candidate.
