Three Unlikely Successful Features of D
summary
Shows three concrete D-language wins: scoped imports let definitions carry their own dependencies, cutting import latency by 4.45x (down to ~64 ms), shrinking object files and speeding links; a relaxed purity model with compiler purity deduction treats mutation of local/transitive state as safe, enabling efficient, analyzable pure-style code and memoization; and compile-time string mixins and regex compilation generate specialized parsers/automata that outperform generic engines (benchmarks beat re2 in common patterns).
