I did not know of this package before, but it sounds useful to me and I 
think there are many places in my code that could benefit from this 
package.

  However, if the package is included in the platform I would prefer to 
have it converted to plain Haskell 98 first, which should not be too hard. 
E.g. the TypeSynonymInstances and FlexibleInstances are certainly required 
by (instance FoldCase String) but can be avoided by a helper type class:
