+ * @todo Proposal: This class does far too much. It should have only 1 task: Collecting
+ * the DQL query parts and the query parameters (the query state and caching options/methods
+ * can remain here, too).
+ * The actual SQL construction could be done by a separate object (Doctrine_Query_SqlBuilder?)
+ * whose task it is to convert DQL into SQL.
+ * Furthermore the SqlBuilder? can then use other objects (Doctrine_Query_Tokenizer?),
+ * (Doctrine_Query_Parser(s)?) to accomplish his work. Doctrine_Query does not need
+ * to know the tokenizer/parsers. There could be extending
+ * implementations of SqlBuilder? that cover the specific SQL dialects.
+ * This would release Doctrine_Connection and the Doctrine_Connection_xxx classes
+ * from this tedious task.
+ * This would also largely reduce the currently huge interface of Doctrine_Query(_Abstract)
+ * and better hide all these transformation internals from the public Query API.
+ *
+ * @internal The lifecycle of a Query object is the following:
+ * After construction the query object is empty. Through using the fluent
+ * query interface the user fills the query object with DQL parts and query parameters.
+ * These get collected in {@link $_dqlParts} and {@link $_params}, respectively.
+ * When the query is executed the first time, or when {@link getSqlQuery()}
+ * is called the first time, the collected DQL parts get parsed and the resulting
+ * connection-driver specific SQL is generated. The generated SQL parts are
+ * stored in {@link $_sqlParts} and the final resulting SQL query is stored in
+ * {@link $_sql}.
