I have found myself using pipes many times in Elm, because they make the code so much more readable. Now I understand why!

I haven't seen an autocomplete that works on pipes. But with a good type system, it is technically possible to list all compatible functions that take "noun" as first parameter.

Sometimes you supply partially applied functions (also with pipes in noun->verb order) and that's not so easy to match:

noun |> verb1 |> (otherNoun >> verb2) |> etc

But perhaps even functions that take "noun" as nth parameter could be suggested.

And other languages, such as Forth; don't need one.

    list map filter odd sum

Huh. I would've expected it to be `odd filter`, not `filter odd`.

Interestingly enough, the now standard data manipulation package in R, dplyr, uses pipelines.

Good to learn me some F#, looks like Elixir.
