[erlang-questions] Pipe Operator in Erlang?

I agree with the general feelings of the thread. F# relies on currying.
Elixir relies on macros (it is actually closer to the thread operator found
in some lisps).

Also F# has most of its standard library expecting the "subject" as last
argument (due to currying). Elixir defaults to the first argument. Erlang,
for better or worse, has them mixed (see binary and lists modules).

For those reasons I don't think this feature makes much sense in Erlang. It
is also hard to have elegant currying when functions are identified by name
and arity. I believe Joxa is the only language in the Erlang VM with
currying but they dropped the fun name/arity bit (citation needed).

Language features are like a Jenga game, all the pieces need to fit
together neatly, otherwise you have a crumbling mess.
