Random meditation: I worked through a lot of the early exercises in Haskell, and partly to learn Haskell. I did a lot of things a "silly" way - didn't use the Vector libraries at all, for example. I learned a lot from doing that, and I wonder if a shiny set of Haskell examples using half of Hackage would provide the same learning experience.
Also: do you have a set of Perl examples? If not, I'd be happy to put them together.
Oh, these links are for the solutions? I thought that clicking on a language should take me to a code submission page for that language where my submission will be judged against different test cases.
Ruby should go up Wednesday. Tomorrow I know Python and C++ go up, and hopefully Haskell.
