Haskell is lazy-by-default and designed around lazy evaluation, whereas most
other languages are strict by default, designed around strictness, and make
you do extra work to get laziness which you then may lose rather easily.
Sometimes it's as easy as using an iterator, other times it means passing
around closures and invoking them at just the right time.
