I would propose :
return (
fact@(n) (
n<=1 ?
1 :
n*fact(n-1)
)
);
Wouldn't that do the trick? I think that the @ char is not allowed in an
identifier in ES5, which mean it would not introduce any compatibility
issue.

one thing that stands out in your proposal is that there doesn't appear to
be any way to write a recursive arrow function.
Here is one way it might be done:
higher(->: fact (n) n<=1?1:n*fact(n-1));
or possibly
higher(->@ fact (n) n<=1?1:n*fact(n-1));
(in either case the 3 character arrow sequence would be one token)
