try/catch/else

[Alan Plum]

Not quite. If the `else` (or `nocatch`, whatever) block throws, it would
bypass the `catch` block but still hit the `finally` block the same way
an exception in the `catch` block would:
* if `a` doesn't throw: a, b, d
* if `a` throws: a, c, d
* if `b` throws: a, b, d
* if `a` and `c` throw: a, c, d

This is analogous to this promise equivalent:

```
console.log("a");
a()
.then(() => {
    console.log("b");
    return b();
}, () => {
    console.log("c");
    return c();
})
.finally(() => {
    console.log("d");
})
```

(note the use of both arguments to `then`)

Your reading wouldn't really provide anything that can't be done by
simply moving the else block's content into the try block.
