There is a good reason for that. It's because of semicolon insertion. You'd
break things if you tried to "fix" it.
Folks write code such as:
function f() {
...
}
(a + b)....
and this would turn the expression into a function call.
Another issue is that the function name (the "f" in this case) does entirely
different things depending on whether it's a function expression or a function
definition.
