Object-Oriented Programmer.

A species that frequently finds Haskell type classes and polymorphism
very confusing.  (Hint: the similarity between Haskell type classes and
OO classes pretty much begins and ends at the name.  Similarly for
Haskell/ML polymorphism and OO polymorphism.  They have points of
similarity, but on net the best plan is to simply never reason
analogically from one to the other.)
