| 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 in 1.1.6/: |
| |
| * Relaxed an unnecessary strictness annotation in the fast implementation |
| |
| /Changes in 1.1.5/: |
| |
| * Both implementations now work on Hugs; the fast implementation ascends |
| from the ranks of completely unportable black magic to being merely |
| /mostly/ unportable black magic. |
| |
| /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 the 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. |
