try/catch/else

[Augusto Moura]

I see this operator quite confusing, in my opinion it's a best practice
treat the functions (and errors) separately. If you want to ignore the
second error you can even create a `silent` helper.

```js
const treatedShowSuggestions = (suggs) => {
  try {
    showSuggestions(suggs);
  } catch (e) {
    // treat error
};

try {
  const suggestions = await fetchSuggestions();
  treatedShowSuggestions(suggestions);
} catch (e) {
  alert('Failed to load suggestions');
}
```
or
```js
const silent = (fn) => {
  try {
    fn();
  } catch (e) {}
};

try {
  const suggestions = await fetchSuggestions();
  silent(() => showSuggestions(suggestions));
} catch (e) {
  alert('Failed to load suggestions');
}
```

This isn't even a workaround, it's just the right approach for what you
want. If you wanna to evict the separated functions you can just inline the
try/catch in the main function.
