Haskell lets you easily create "infinite" lists, which is a powerful and
useful feature. But if you abuse that feature, you'll have problems,
because you don't have infinite memory. The further you traverse an
infinite list, while maintaining a reference to its head, the more
memory you use. It'd be a stretch to characterize this as "hard".
I don't see much connection between this and the space efficiency of
I feel a bit like we're discussing a monster under the bed: "i bet it's
huge! its teeth must be so sharp!" Maybe we should just look under the
bed, i.e. implement what we need and see what happens?
