Abstraction Patterns: Making Code Reliably Better Without Deep Understanding
summary
Codebases reveal missing structure: spotting literal magic numbers and converting them to named constants, grouping seven boolean flags into a single options struct, replacing long switch-on-type blocks with small derived classes, and extracting 50–100‑member monster classes into focused subobjects all reduce bugs and cognitive load. Uses concrete tools and APIs: chrono and <numbers> for constants, std::any_of/std::find rather than raw loops, build‑system header selection for platform calls. Claims: these missing abstraction cues — including load-bearing blank lines and using any_of/find/rotate — measurably shrink complexity.
