Hello,
it is my pleasure to announce the DecisionTree package. It provides
an implementation of the ID3 algorithm [1] and can be used to

If all tuples in Haskell were unlifted then () would not be such a special case.
But I would argue against unlifted tuples, because that would make
tuples (or single constructor data types) different from other data
types; adding a constructor to a type could totally wreck laziness of
a program
