I understand what you're writing above but I think that ties this
proposed short syntax for functions (or lambdas) to something the
arrow syntax is not tied to and so makes it a "do you like apples or
oranges?" choice. In another thread, some people were suggesting {||}
as an exact alternative to the thin arrow.
