For instance, in a script which does software installs:\n\n```\nUserName = \"Jaykul\"\nDownloadTo = \"C:\\Users\\{UserName}\\Downloads\\Installers\"\nConfigFolder = \"{DownloadTo}\\Configuration\"\n```\n\nCurrently we support tokenizing only for folder names.  Maybe we could make it work for other settings by reference, like `{Settings.UserName}` by requiring them to be prefixed with `Settings.` and then resolving them after import (like paths in PoshCode) iterating to allow multiple reference levels:\n\n```\nUserName = \"Jaykul\"\nPaths = @{\n   DownloadTo = \"C:\\Users\\{Settings.UserName}\\Downloads\\Installers\"\n   ConfigFolder = \"{Settings.Paths.DownloadTo}\\Configuration\"\n}\n```\n","author":{"url":"https://github.com/Jaykul","@type":"Person","name":"Jaykul"},"datePublished":"2014-10-27T20:56:33.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/3/Configuration/issues/3"}
