What do you mean by “as it is currently”. Currently, this is a syntax error! (“parse error on input ‘do’”). Only with the proposed addition, it becomes an argument to foobar. And it is not hard to reason about this: "x" is lined up with the "do", so it is a sibling, not a child, in the AST. Hence, both are arguments to foobar. This is another good instance of how the (by me) beloved feature of “parenthesless arguments”, which so far is only available for the last argument of a function (using the “$” idiom), would now be possible for every argument of a function.
