Keynote: Ghosts of Ruby - A Neo-Dickensian Explication
summary
Walks through concrete version differences: compiles Ruby 1.0 by commenting out failing bits, shows a shuffled deck implementation that uses a custom rand-based shuffle and a deck-of-cards demo using an enumerator hooked to deal, and highlights 1.9 additions like each_cons reverse_each cycle and enumerators that proxy other methods (map without block returns an enumerator, select on hashes returns a hash). Notes basic_object atop the hierarchy, the stabby lambda syntax, and 1.9 block-variable scoping that no longer clobbers outer locals.
