 BenchmarkDotNet doesn't support setup/cleanup method for a single method invocation (*an operation*),
   but you can perform only one operation per iteration.
 It's recommended to use `RunStrategy.Monitoring` for such cases.

 A method which is marked by the [`[IterationCleanup]`](xref:BenchmarkDotNet.Attributes.IterationCleanupAttribute)
   attribute will be executed only once *after each an iteration*.
