You can also use Dump

as a function:



let nums = [1; 2; 3; 4; 5]
Dump nums
nums |> Dump
(* ... *)

Apart from the method already set .Dump()

, you should know that it is also automatically called when you write the collection (and other types) in the console:

let nums = [1; 2; 3; 4; 5]
Console.WriteLine(nums);

will also give you a dump.

This can be used in the middle of a workflow as well, as it returns its input.

let DumpHelper (caption:string) a =
 a.Dump(caption)
 a
