// Measuring performance is an important part of writing So programs.
// The `so/testing` package provides the tools we need to write
// benchmarks, and the `so bench` command runs them.

// By convention, benchmark code lives in the `bench` subdirectory of the
// package we are testing - that's where the `so bench` command looks for it.
//
// Do not name the file with benchmarks `main.go` - that file will be
// auto-generated when you run `so bench` and will contain the `main`
// function that runs the benchmarks.
//
// Do not use the `_test.go` suffix for benchmark files.
