Lambda the Ultimate

We mentioned O'Haskell previously on LtU, but a recent discussion of OOP vs. FP vs. everything made be to believe that it's worth to remember this (unfortunately unsupported) programming language.

It's instructive to read the rationale for this PL, as it helps to see how OOP and FP solve similar tasks in orthogonal (or just different) ways.

Note that the author of O'Haskell abandoned it in favor of Timber.
