You might want to make a local version of ErrorT in your library, to avoid the silly 'Error' class restriction. This is pretty easy; just copy it from the 'transformers' or 'mtl' package.
Yes, I wonder why mtl is not updated so as to remove this restriction.
Presumably because its in "maintenance mode" (i.e. it only gets changed/updated to reflect changes in GHC that might affect it and the API is frozen). -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
