The source code for the current version of `Typing Haskell in Haskell'
is now available from: http://www.cse.ogi.edu/~mpj/thih/ It is, of
course, written in Haskell 98, and has been tested and developed using
Hugs 98.
For those who don't know, `Typing Haskell in Haskell' is an attempt to
produce a formal specification for the Haskell type system in the form
of an executable Haskell program. A paper describing this system was
presented at the Haskell workshop in Paris last Friday, and is also
available from the web page above.
I hope that `Typing Haskell in Haskell' will be a useful resource for
anyone interested in understanding the Haskell type system, or in
experimenting with new extensions, and I welcome any feedback. I should
also mention that this is an ongoing project, and further revisions of
the specification/program are already planned or in progress.
All the best,
Mark
