10.4.5 Record and Array Aggregates
Use a sequence of assignments for an aggregation when measured performance indicates.
Determine the impact of using an aggregate versus a sequence of assignments. Using an aggregate generally requires the use of a temporary variable. If the aggregate is "static" (i.e., its size and components are known at compile- or link-time, allowing link-time allocation and initialization), then it will generally be more efficient than a sequence of assignments. If the aggregate is "dynamic," then a series of assignments may be more efficient because no temporary variable is needed.
See Guideline 5.6.10 for a discussion of aggregates from the point of view of readability and maintainability.
See Guideline 10.6.1 for a discussion of extension aggregates.
