+       * expression.cs (Cast): Overload DoResolveLValue so we can pass
+       resolve our casted expression as an LValue.  This triggers the
+       proper LValue processing that is later required by Assign.
+
+       This fixes 72347.
+
        * cs-tokenizer.cs (pp_and): recurse on pp_and, fixes #61903.
