Also, lazy lists are really an idiom from languages that are very comfortable with lists, i.e. mostly functional languages (Haskell, for example). The same idiom is, I believe, really not as practical in C++ and other imperative languages. Modern C++ uses iterator ranges as the primary concept for generic handling of finite and infinite sequences, and there already are function-backed input iterators. The second concept used is input streams.
There are already function-backed input iterators in Boost?
I know there are function-backed output iterators, but not function-backed input iterators.
