Prying inside a pipeline

[rap...@eficienciafiscal.com.br]

Hi there,

A friend of mine asked me how to IEx.pry inside of a pipeline, I said there is no builtin functionality for this, so I sent him this code:

defmodule Debugger do
  def pipry(value) do
    require IEx

    IEx.pry()

    value
  end
end

It worked for him, but I wonder if such functionality should be builtin into the language, something like a `IEx.pry/1` or `IEx.pipe_pry/1` function.

What do you guys think? If this sounds like a good feature for the language, I would love to hear your input so I can give it a go and submit a PR.

Well if `tee` gets added then this is yet another use case for it.  ^.^

Well, `tee` was not added to the core. So for now, one can use the `plumbing` package. https://hex.pm/packages/plumbing
