First, it's not a keyword, it's an intrinsic operator.
Second, even if it was a keyword, keywords are not reserved
in Fortran.
Both intrinsic operators and keywords must be use in ways consistent
with the rules of Fortran or they're likely to be ambiguous or just
wrong. The rules of Fortran don't permit the above to be interpreted
as a subobject name. Implementations the permit such extensions
should do so carefully and not misinterpret the above. I wouldn't
use the extension anyway. Nor would I recommend that anyone
else do so.
