+By "cannot be performed", I meant that it cannot happen in a single
+explicit cast according to the rules of the standard.
+
+Allowing this type of conversion alone, and ensuring that the standard
+is adhered-to in other cases, will complicate the code, IMHO.  Also,
+as you show, it's relatively trivial to fix the issue.
+
+I'll try to see if I can add a warning about this case.
