This is kind of neat. My question is, should something like
this function be included in std.range? Either way, it turned
into an example of something cool you can do with D.
It really looks like "iterate" combinator from Haskell's standard
library:
iterate :: (a -> a) -> a -> [a] Source
iterate f x returns an infinite list of repeated applications of
f to x:
iterate f x == [x, f x, f (f x), ...]
http://hackage.haskell.org/package/base-4.8.2.0/docs/Prelude.html#v:iterate
(which could be a hint to stdlib-includability and naming)
