Implementation of Overloaded Record Fields based on current GHC proposal. It is built on top of functionality that is included in GHC 8.0.1, but it works on older GHC versions as well. Most importantly, this library provides Template Haskell functions for automatic deriving of instancess for HasField and ModifyField type classes. With these instances overloaded fields can be used directly as getters and lenses.

See README for usage examples.
