Hello,

You may submit a public comment on the committee draft
of the proposed Fortran 2008 standard by sending an email
to f2008-ballot-comments-ext@sun.com

If you are outside the USA, you may prefer to comment
through your national body.  You are welcome
to comment to J3.

The draft may be downloaded from J3's web site
at www.j3-fortran.org as 08-007r2.pdf
or from WG5's web site at n1723.pdf
or from INCITS's web site at pl22.3.incits.org
as SC22 N4319.

Public comments may be submitted from 2008 June 6
until 2008 July 6.  J3 will act on comments
at its August 2008 meeting.

Cheers!

Yes, send as many comments as you want.

It helps J3's internal processing to keep
any one comment to one topic, or, for editorial comments,
to one clause of the draft.

Just FYI, the following is what I just submitted to that address. This
shouldn't be any great shock to those who have read my previous postings
here, but I went ahead and made it a formal comment:

This is a public comment on the f2008 CD. While I have perused the CD, I
have no detailed technical comments at the moment. My only comment is
the general one that it is simply too early to be processing the next
Fortran standard. I realize that the processing was already somewhat
delayed, but insufficiently so in my opinion.

It's not a failure, it's simply true that too few resources
are being spent to implement f03 compilers.

OTOH, how many f03 C++ compilers (complete!) are there?
By most counts I've heard, exactly 1. How many C99
compilers (complete!) are there? Very few.
OTOH, there is a complete Ada05 compiler.
(The other two Ada compilers are complete Ada95,
with Ada05 features.)
(FTM, how many complete C# compilers are there? 1)

Yeah. I don't actually think it is a failure either. I just mention this
as the alternate interpretation to the one I think more accurate, which
is...

On a tangent, there is a way that F03 implementation could have been
sped up. In the C++ world there is a company that sells a parser,
which is implemented with a good interface for attaching it to
compilers. If such a gizmo existed in the Fortran world, I'm sure that
many vendors would happily pay to use it, and it would reduce the cost
of F03 significantly.

Now if gfortran had been farther along already, that probably would
have sped things up a bit, through embarrassment. But it wouldn't
reduce the implementation cost, except perhaps from some testcase
writing.

Parsing Fortran is trivial. Lexing Fortran is more
complicated, but it is a well understood problem.
Reducing the time required to write parsers and lexers
for Fortran 2003 to zero would not make much of a dent
in the total effort needed to create a Fortran 2003
compiler.

Yes, but those stuck with front-ends derived from the hard-to-modify
Cray FE don't find trivial things trivial to implement. Perhaps you've
moved off of it, or rewritten it.

FWIW, the last I checked (last month) I also found the IBM compiler was the furtherest
along to full F2003 compliancy with only parameterised derived types still to be
implemented in the v11.1 release. I believe the IBM term is "enhanced compliance" :o)
