+The `cfg.tokenlist` does not always match the raw input code exactly. For instance:
+ * The `cfg.tokenlist` is preprocessed.
+ * There is no typedefs in `cfg.tokenlist`.
+ * C++ templates are instantiated when possible in `cfg.tokenlist`.
+ * Variable declarations are sometimes splitted up.
+ * If you don't write {} around the body for a if/else/while/for etc then those are inserted in the `cfg.tokenlist`.
