 Note that being terse, or avoiding verbosity, is a non-goal. This is in part because of the constraints that C imposes. But it also aids with clarity and conceptual simplicity, as the issue of correlated samples illustrates in the next section.
 
-Caveats: Parallelism might hide monsters. The histogram function is pretty but was created with the aid of GPT, and so might have errors.
