This is slightly misleading. In the following code:
```js
try {
doStuff();
} catch (e) {
// handle somehow
}
function doStuff() {
// do some stuff
}
```
the code inside `doStuff` is still optimized by V8. The only code that is
not optimized is that directly inside the `try` block, i.e. the call
`doStuff()` itself. I'm not sure if optimizations matter, or are even
possible, for code that simple---so if you follow a pattern like this,
try/catch should have no performance impacts.
