Be careful, this may cause a crash in standard-compliant but unusual code where the body of a `switch` statement is *not* a compound statement.

For example code like
```
switch (get_value()) case 0: case 1: run_foobar();
```
is completely valid; and here the body of the switch statement is a `CaseStmt` (which has another case statement as a child).
