For example:
- `(@$region)` will show nothing if the variable `region` is `None`, otherwise `@` followed by the value of region.
- `(@$region)` will show nothing if the variable `region` is `None` or empty string, otherwise `@` followed by the value of region.
- `(some text)` will always show nothing since there are no variables wrapped in the braces.
- When `$all` is a shortcut for `\[$a$b\] `, `($all)` will show nothing only if `$a` and `$b` are both `None`.
This works the same as `(\[$a$b\] )`.
