I agree a missing body is usually weird; the only case that really makes
sense is `=>`, which is especially useful in default parameter lists:
```js
function tryCatchFinally(tryF, catchF = =>, finallyF = =>) {
// ...
}
```

My perspective: I don’t see a use case for a missing body, but a missing
parameter list would be very useful – to delay the execution of a block of
code. It also makes much sense visually:
2. (x, y) => { ... }
1. x => { ... }
0. => { ... }

A useless parameter is an option:

This seems to be an argument in favor of making the params completely optional.
The fact that throwing in a useless param is more concise than having zero
params (due to paranthesis requirement).
I think the semicolon hazard is enough to make omitting the body questionable,
but omitting the params is an easy win with no downside.
