I just filed report PR 8797 stating that the above syntax should not be
accepted, or alternatively that the "extension" should be documented in
the manual. I guess I lean towards the first alternative. Note also that
using -pedantic yields a _warning_, not an error on the code above, so I
guess having a separate report is justified.
