That's pretty nice, but until (complete) F2003 compilers become more
commonplace, I think I will stick with F95. Still, I look forward to
getting my hands on a F2003 compiler that implements the full standard.

The conversion to F2003 once a compiler is available is trivial. Many
times people waste far more time trying devise a "standard conforming"
solution when a trivial extension such as this will suffice for the
particular problem at hand.


Yes, but where I work, there are various Fortran compilers and the code needs to work on all of them. Of the ones we have, I think only g95 and gfortran have any F2003 extensions at all. We usually only use these for development because the executables are slower than our other compilers.
