Hi everyone,
I was writting some docs, and I realize I don't know how to do this.
when using docstests, we can do
iex> ex = fn -> IO.puts(:elixir); :rocks end
...> ex.()
#=> elixir
:rocks
but what is the proper way to do this when it is not a doctest?
How do i differentiate what written to std_io, from what it's being
returned.
ex = fn -> IO.puts(:elixir); :rocks end
ex.()
thank you
