In Microsoft's [F# samples](http://go.microsoft.com/fwlink/?LinkID=124614), they use the ">>" operator as follows:

```
test |> Seq.iter (any_to_string >> printfn "line %s");

```

What does the ">>" operator do in this context? Is each item of the sequence (an array in this case) get passed to `any_to_string` implicitly? Is this similar to `(fun item -> printfn "line %A" item)`?
