Laziness is a useful property, but it is not without its disadvantages,
particularly in terms of predictable performance. For example, code
involving lazy seqs is more prone to memory leaks than iterators are.

Eager evaluation is a simpler approach, in terms of both code and
predictability. Eager evaluation fails fast, and has predictable
performance characteristics. Laziness is a useful tool to have in one's
arsenal, but I don't believe it should be the norm, as most of the time
it's not necessary.

Of course, most Haskell users would probably disagree with me :)
