The current reverse pipe (<|) is left-associative and same precedence.
Left-associativity is "unnatural" for reverse pipe making it's usage harder, ie this doesn't compile: let x = abs <| abs <| 2;
In addition sharing the precedence of |> makes mixing them harder.
There are already existing languages with such an operator ie Haskell and operator '$'.
I propose adding a right-associative low precedence reverse pipe operator to F# in order to improve reverse-piping.
I know some people disagree with reverse-piping but I personally like it as it can be used to remove parantheses. To me excessive amount of paratheses makes code harder to read (I guess this is the reason I struggle to enjoy LISP).
