"A major limitation of the pipe operator is that all the callables in the chain must accept only one required parameter.

For built-in functions, if the function does not accept any parameters, it cannot be used in a chain. For user-land PHP functions, passing a parameter to a function that does not accept any parameters does not cause an error, and it is silently ignored.

With the pipe operator, the return value of the previous expression or the callable is always passed as the first parameter to the next callable. It is not possible to change the position of the parameter."

In the light of these limitations I would not call the Elixir implementation "slightly fancier".

I'm not so sure I'll be upgrading my local PHP version just for this but it's nice that they are adding it, I'm sure there is a lot of library code that would look much better if rewritten into this style.
