- Consume iterators with for range instead of discarding with _ = Previously iterators were created but never consumed, giving misleading performance results (~0.3 ns/op) that only measured iterator creation - Add BenchmarkItDropLastWhile for testing DropLastWhile performance - Add BenchmarkItTrim for testing Trim performance - Add BenchmarkItTrimSuffix for testing TrimSuffix performance - Replace for better readability `for i := 0; i < n; i++` with `for i := range n` This fix ensures benchmarks measure actual iterator execution time rather than just iterator creation time, which is critical for lazy iterators that don't execute until consumed.
