I do not understand last_ ...

[Massimiliano Gubinelli]

Hi all,

 I'm a bit puzzled by the following output:

Prelude> import qualified Streaming.Prelude as S

Prelude S> S.last $ S.each [1..100]

Just 100 :> ()

Prelude S> S.last $ (S.slidingWindow 10) $ S.each [1..100]

Nothing :> ()

Why in the second case I obtain a Nothing?

And what is a natural way to output the structure of a Stream  ?

Thanks a lot!

Max
