## Hi - A Haskell interpreter

There aren't nearly enough toy Haskell interpreters. Here's my attempt

at one. Some of the design is fleshed out in the notes directory.

This interpreter only handles a single file, it doesn't attempt to

handle modules or imports or anything like that. Aside from this

though it is a reasonably complete implementation of core Haskell 98.

The interpreter follows roughly the pipeline

    Parsing (haskell-src-exts)

                ⇓

        Pruning the AST

                ⇓

     Type Checking and similar

                ⇓

       Strip Syntactic Sugar

                ⇓

        Closure Conversion

                ⇓

         Lambda Lifting

                ⇓

    STG Machine (PUSH-ENTER style)
