safely evaluate pure Haskell expressions

 Mueval is a Haskell interpreter. It uses the GHC API to evaluate arbitrary
 Haskell expressions. Importantly, mueval takes many precautions to defang and
 avoid "evil" code. It uses resource limits, whitelisted modules and Safe
 Haskell, special Show instances for IO, threads, processes, and changes of
 directory to sandbox the Haskell code.
 .
 It is, in short, intended to be a standalone version of Lambdabot's famous
 evaluation functionality.
 .
 This package provides a library for the Haskell programming language.
