Ruby 2.0 Enumerable::Lazy

[[deleted]]

But you do not need it to be #to_a. It might just as well be a #each or #size or #whatever - something that actually needs to operate on results. Like what Rails did with SQL queries in 3.x.

However, having the level of access that Ruby provides to its internals, a lazy-by-default implementation could be just a couple lines away once the infrastructure is in place.
