Re: [...] my rant on reductions...



Amen!

There have been reasonable and unambiguous proposals in this and many other areas where the draft is failing. Unfortunately, critical components of the committee have not cared to understand the issues, the proposals, or the state of the art outside the committee. The committee will find a solution consonant with 21st century specification technology, or it will be bypassed by folks like the Open Source Numerics groups Dan recently responded to.

Yes, these are important issues. Yes, many of the proposals to date address pressing problems of portability, performance, and unambiguous implementation. No, there is no solution in Fortran II. No, there is no DWIM button.

Sorry, guys.

David Bindel and I compared a few possible implementations of the scaled alternate exception handling pretty much exactly three years ago. We discussed some of the options' performance considerations on current platforms and made implementation recommendations. We had running code and timings. We also included a "scarecrow proposal" recommending a scaled type, which is the right way to solve this problem from (what should be) the 754 level.

Now I'm more interested in fixing the basic model
so these options can be expressed clearly to implementors. But that work is in the unfunded
queue.
