My name is Sergio, some of you know me, some others don't ;) I'm a Spanish Ruby developer living in Berlin for around a year now, and I want to make my first presentation at RUG::B in the next meeting if possible.
I'd like to make a review about what is laziness (or its slightly less cool but far more accurate name, lazy evaluation) in programming. Also, why is it cool, why is it useful sometimes. In what languages do we find it, and what can we do with it in Ruby. That's it :)
