description:
  This package provides an implementation of the ideas presented in the paper
  \"Functional Pearl: Implicit Configurations\" by Oleg Kiselyov and
  Chung-chieh Shan. However, the API has been streamlined to improve performance.
  .
  The original paper can be obtained from <http://www.cs.rutgers.edu/~ccshan/prepose/prepose.pdf>
  .
  /Changes from 0.5 to 1.1/:
  .
  * Much faster implementation available that is about 50 /times/ faster than 0.9 and which runs
    purely on black magic. This version is now used by default. To turn it off install with the
    'slow' flag. If you encounter a problem with implementation, please contact the author.
  .
  * Removed @ReifiedNum@, @reflectNum@, and @reifyIntegral@; @reify@ and @reflect@ are
    about 3 orders of magnitude faster than the special case combinators were.
  .
  /Changes in 0.5/:
  .
  * Generalized the type signatures in reflect to allow you to pass any type
    with kind @* -> *@ wrapped around the desired type as the phantom type
    argument rather than just a @Proxy@.
  .
  /Changes in 0.4/:
  .
  * Converted from `Data.Tagged` to using `Data.Proxy` for reflection. This
    reduces the need for helper functions and scoped type variables in user
    code.
