Hello, I want to study the internals lof Hugs, but the only document I got is: The implementation of the Gofer functional programming system http://web.cecs.pdx.edu/~mpj/pubs/goferimp.html I see Gofer is the predecessor of Hugs, but I am not sure how much the code base has been changed since then. Are there more recent documents on the internals of Hugs? Regards, Kwang Yul Seo
