 Define and return, but do not tune or run, a `Benchmark` that can be used to test the performance of `expr`. Relevant manual documentation can be found [here](manual.md#benchmarking-basics) (for valid `kwargs` values, see [here](manual.md#benchmark-parameters) specifically). If used in local scope, all
 external local variables must be interpolated.
