    crop(resize(first(images), 100, 100), 25, 25, 75, 75)

this will likely get better when julia implements proper pipes, IIRC coming soon in the plans (like elixir does):

    images
    |> first
    |> resize(100,100)
    |> crop(25, 25, 75, 75)

If the language bothers to implement an inspect method (again, like elixir) this is vastly superior to . chaining because you can do this:

    images |> inspect
    |> first |> inspect
    |> resize(100,100) |> inspect
    |> crop(25, 25, 75, 75) |> inspect

trivially with multiline cursor (and also trivially ninja'd out with multiline cursor) and have full introspection on the evolution of your data through the pipeline. This is impossible in oo languages (well maybe you could do it in a prototyped language) because dispatch of the .inspect method would have to be implemented on each object.
