I had a little experiment along the lines of "A Package Versioning Policy Checker" a few months ago. I got as far as using Haskell-src-exts to extract module export list, but didn't work out out a hashing scheme for the actual type signatures.
I've been thinking of doing something similar for a year or so now, but there's one big problem that I can think of: how to deal with functions that don't have an explicit type signature in the source. My understanding is that to derive these signatures at "checking time" would require using something like the GHC API, which immediately reduces the "niceness" and portability of such a tool/library. -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
