The Little Things: Why you should always have benchmarks ready

At the end of January, I removed some low-hanging allocations from Catch2. This meant that running the SelfTest binary in v3.3.1 made 8k fewer allocations, but it also made section tracking in v3.3.1 ~4x slower. This post is about how that happened and what we can learn from this.
