If anyone is interested in the theoretical background to the thrush combinator, a.k.a. "|>", here is one using Ruby as the implementation language:

Being a concept which transcends programming languages, a search for "thrush combinator" will yield examples in several languages.

I find this [1] from this [2]. Seems like a good explanation. It doesn't exist on Wikipedia though.

A key thing to keep in mind is that the thrush combinator is a fancy name for a simple construct. The semantics it provides is a declarative form of traditional function composition.

For example, given the expression:

  f (g (h (x)))

The same can be expressed in languages which support the "|>" infix operator as:

  h (x) |> g |> f

There are other, equivalent, constructs such as the Cats Arrow[0] type class available in Scala, the same Arrow[1] concept available in Haskell, and the `andThen` method commonly available in many modern programming languages.
