Keeping it Simple With Go
summary
Argues Go trades expressiveness for simplicity and explicitness, giving concrete advantages: arrays are value types and slices are lightweight views, methods can attach to base types, and structural typing plus embedding replaces fragile inheritance. Shows fast builds with go get/go build and demonstrates an arena allocator implemented in Go to keep nodes contiguous; contiguous layout reduces cache misses (example: fragmented layout yields ~4 misses vs 1–2 for packed data), so manual memory layout control measurably improves CPU-bound performance.
