  \\[4ex] Haskell-style type classes with Isabelle/Isar}

\begin{abstract}

  This tutorial introduces the look-and-feel of Isar type classes

  to the end-user; Isar type classes are a convenient mechanism

  for organizing specifications, overcoming some drawbacks

  of raw axiomatic type classes. Essentially, they combine

  an operational aspect (in the manner of Haskell) with

  a logical aspect, both managed uniformly.
