Std.App.Config.Source

type

This declaration introduces a public type.

What it does

Where a setting came from.

Kept beside the value rather than discarded, because a program refused over

a setting should be able to say which of four places supplied it. Without

this, the answer to "why is the port 9000" is a search.
