 Gaby, Volker,
 
 let's settle this matter:

 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.
