An introduction to the Julia language, part 2

Ocaml also uses the left-associative |> notation. It's a nice homage to the POSIX shell pipe, i.e. piping output from one function into another. But it's certainly strange to see that notation in a language aimed more at scientists and mathematicians, who probably won't have seen a shell pipe anyway, and where they're likely to be more familiar with right-associative composition.
