It had a lot of issues which meant it wouldn't build anywhere, where at least the Hackage version worked at some point. I spent this evening working on fixing issues (rewriting the show package to use QuickCheck 2 rather than QuickCheck 1 was not fun!) and have uploaded a lambdabot and show that compile for me on GHC 6.12.1

The show package almost compiles on GHC 7, but:

* You need to loosen the base upper bound to < 4.4 * If using base >= 4, you need to depend on the syb package as well (current version 0.3)

Would this break GHC 6.12 builds? Since I do not have GHC 7 installed and, given the breakage I experienced when I installed it the other day and tried to cabal-install my usual tools, will not have it installed any time soon, I am leery of any GHC 7-related changes. data-memocombinators is only the tip of the iceberg; I believe much of lambdabot would need modifications. (Apparently Control.OldException has gone away, which alone guarantees many changes.) So there wouldn't be much point to changing show. -- gwern http://www.gwern.net
