As we do more and more type-level programming, the lack of a decent kind system (to make sure that your type-level programs make sense) has become an increasingly pressing issue. If all goes well, GHC 7.4 will take a substantial step forward: 17 * First, all simple data types (including lists and tuples) will automatically be "promoted" to be kinds as well, a design inspired by Conor !McBride's Stra chclyde Haskell Extension [[http://personal.cis.strath.ac.uk/~conor/pub/she/ SHE]].
