He can't find the documentation for the pipeline operator. And he posted examples from ReasonML rather than F# and OCaml. For reference this is the documentation for the pipeline operator in F#: https://msdn.microsoft.com/visualfsharpdocs/conceptual/opera... It's kind of sad that people nowadays know only JavaScript and languages from the web ignoring the original language from where the syntax come from. I would not be surprised if he posted some purescript instead of Haskell. As per the "modern" languages in the title the author has no idea about what he is speaking about. OCaml is 21 years old, just 1 year younger than Java, I would not call it a "modern" language. But if someone thinks that the code he posted exists only in ReasonML than that one can be defined a modern language. I rarely criticise blog post, but this one is just not well written and the author has no idea about this subject.
