Question: Why allow empty statements?

This is more of a question than necessarily a bug in the spec.

Linting options (https://dart-lang.github.io/linter/lints/empty_statements.html) flag the usage of `;` as in

```
print("Hello World");
;
```
as unnecessary and state that it should be avoided. This seems self-explanatory.

It further says that
> Empty statements almost always indicate a bug

What I am wondering: When is that not the case? When is it ever useful to have an empty statement using `;`?

Start with the empty_statements lint page linked in the issue, then review the Dart language specification's treatment of empty statements and semicolons. The issue names no file or test; completion would require an agreed explanation of valid uses, or a clarified specification or lint recommendation.
