Edit Question
Title
Body
I noticed in some code in this sample that contained the >> operator: let printTree = tree >> Seq.iter (Seq.fold (+) "" >> printfn "%s") What does the >> operator mean/do? EDIT: Thanks very much, now it is much clearer. Here's my example I generated to get the hang of it: open System open System.IO let read_lines path = File.ReadAllLines(path) |> Array.to_list let trim line = (string line).Trim() let to_upper line = (string line).ToUpper() let new_list = [ for line in read_lines "myText.txt" -> line |> (trim >> to_upper) ] printf "%A" new_list
