ml-w

This package implements a minimal ML-like language to demonstrate how the W algorithm works. The ML module contains the definition of the language in the form of an Haskell data type, plus functions to parse files and pretty print the datatype. The TypeInfer module contains the W algorithm itself. The Main module contains a program that parses and typechecks programs reading from standard input. The library and executable is compatible with GHC and Hugs (to use Hugs with cabal use the flag --hugs).
