This library provides anonymous extensible records using GHC 8.0 features, with the following goals/features: The syntax should be very close to that of Haskell's record system. The library should be simple to use and requires no extra boilerplate to setup. There should be minimal runtime overhead and memory footprint. The library does not require TemplateHaskell to use. It should produce good error messages. Minimal dependencies. Currently, it only depends on packages that comes with GHC. See Data.Rawr for a tutorial of this library.
