This is not elixir pipes. Elixir pipes are sound because they are piping to a function. Piping to a statement is not the same thing and it will become more clear in actual usage just how bad these are. Remember % in js is also modulo, and "test" % "ing" returns NaN. NaN is infectious since basically anything that operates on NaN returns NaN. "test" % "ing" + "ana" returns NaNana . You can quickly see how these pipes (as implemented) are so bad they might as well be language sabotage.
