Thank you very much.. I have learned new things here today.. I am happy that I have found my way back to this forum after some bad bi yearly banning experiences at holy stackoverflow (latest only because I asked a duplicate question)..

I’m often lazy and just put a case between things… >.>

Also you really need to use code tags instead of quotes for bodies of code, you do it like:
```elixir
Code goes here like 2+2
```
Makes:

Code goes here like 2+2

As a possible alternative to writing a full fledged maybe_* function, you can also consider to use a general purpose maybe_if/3 function. I’ve done that in the past when I needed to chain multiple optional steps.

initial_data
|> first_transformation()
|> maybe_if(should_apply_step2, &second_transformation/1)
|> maybe_if(should_apply_step3, &third_transformation_with_params(&1, my_param))
|> another_one()

where maybe_if is defined like this:

def maybe_if(data, true, action)
  when is_function(action, 1),
  do: apply(action, data)

def maybe_if(data, false, _action), do: data
