[PROPOSAL] Pipe operator enhancement

[Aleff Souza]

We all know that the pipe operator is very powerful and elegant, but what I think that is annoying sometimes is that it ONLY passes the result to the FIRST parameter of the next expression. So, I think it'd be nice to have some way where I could choose which parameter the left result would be passed. 

In Example, given a function foo/3:

"Elixir"
|> String.upcase
|> foo(param1, _, param3)

Where '_' is where the result from the previous expression would be passed on.

Hello Aleff,

Proposals that enhance the pipe operator such as this one has been sent multiple times in the past. I recommend you to read the archives and see why they were rejected. If previous proposals were not exactly as this one, the reasons for rejection likely stand.
