Subject: [PATCH] Allow arbitrary strings in string literal union types
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

• Restore `Transform` and `ValueTransform` string union literal types
• Use generics to allow arbitrary strings for parameters with the previously listed types
• Move exported functions to the bottom of the file
