reflection: Reifies arbitrary terms into types that can be reflected back into terms
This package addresses the configuration problem which is
propagating configurations that are available at run-time, allowing
multiple configurations to coexist without resorting to mutable
global variables or System.IO.Unsafe.unsafePerformIO
.
That package is an implementation of the ideas presented in the paper "Functional Pearl: Implicit Configurations" by Oleg Kiselyov and Chung-chieh Shan (original paper). However, the API has been streamlined to improve performance.
There are a handful of tutorials on how to use this library:
Austin Seipp's tutorial Reflecting values to types and back provides a summary of the approach taken by this library, along with more motivating examples.
Arnaud Spiwack's tutorial All about reflection explains how to use this library.

template-haskell | You can disable the use of the `template-haskell` package using `-f-template-haskell`. Disabling this is an unsupported configuration, but it may be useful for accelerating builds in sandboxes for expert users. | Enabled |
