Readme

For a certain class of programs, type-level let is essential in order to be able to write these programs in such a way that they do not result in ghc core that is quadratic in size. Type-level let is not explicitly supported in ghc, but we can encode it. The typelet library provides a type-checker plugin that makes the encoding more convenient to use as well as more effective.
