As already noted, the operator |> is hard to add to the language because it
doesn't work that well.

I'd much rather see a succinct notion for a monadic val/bind where I can
set a monad

M = #monad { val = Val, bind = Bind },
with M do
    X <- foo(),
    Y <- bar(X),

and run inside the monad[0]. Since the language is dynamically typed, you
would have to supply the monad you are building over, but you would be able
to do a lot of the things people request with the |> operator, as it is a
special case.

[0] I've given this very little syntactical thought at the moment, but
hopefully you get the idea.
