Enhance handling of parameters in typeclass constraints: permit to specify any typeclass parameter by name anywhere in a typeclass constraint. This allows to share implementations easily and to give any subset of the parameters in any order in the constraints, whereas we are still restricted to a prefix of the typeclass parameters context when using "positional" specifications.
