Ensuring unused code is run

[Etherian]

In a simple benchmarking script I'm writing I need to ensure the code being benched isn't optimized away. Any suggestions for how? Maybe something involving the IO monad?

I am not sure about the constraints here, but broadly speaking the only true way is to check that the benched code actually produces the expected value. Then you can be reasonably sure that the code actually runs.
