This is entirely possible and normal practice, and is often done by
normal code.

(I am, however, willing to be corrected).

Which rules?

Can you specify what the standard says about this case?
(If it is a numbered constraint, then a compiler is required
to diagnose it.  If it is something like "shall" or "shall not",
then it is up to the programmer to get this right; a good
implementation might catch the error, but it is not
required to do so).=
