+ * }</pre>
+ *
+ * The text after the {@code ->} operator is the conditional subquery that's only included if
+ * {@code showEmail()} returns true. The subquery can include arbitrary characters except curly
+ * braces, so for example you can have multi-line conditional subqueries too.

  * By composing SafeSql objects that encapsulate subqueries, you can also parameterize by
  * arbitrary sub-queries that are computed dynamically.
