Std.Out.Stream

type

This declaration introduces a public type.

What it does

Which of the two streams a printer writes to.

Output is what a program answers with; Errors is what it says about itself.

A program whose diagnostics go to Output cannot have its answer piped

anywhere, which is the reason the two are separate rather than a flag.
