One thing that bit me when I was learning Go was the behavior of the
"defer" keyword:

```
func something() {
  for i := range ... {
    x := open_something_expensive()
    defer release_resources(x)
    do_something(x)
  }
}
```

The problem is that the `release_resources` deferred statements are run at
the end of the something() function, not at the end of each loop iteration.
