Those semantics are extremely error-prone. `(("foo" ^^ "bar") ^^ "baz") !==
("foo" ^^ ("bar" ^^ "baz"))`, and I doubt anyone will remember which
corresponds to `"foo" ^^ "bar" ^^ "baz"`?

Also, the syntax gives the impression that this is a short-circuiting
operator since it is a "doubled bitwise operator" like || and &&, but it
can't be short-circuiting.
