Hi Ed!

Great work: glad to see you slugging away at this.

I think it's past time for this to go in to mainline. I'm hoping that this drop (and the progress since the last drop) will make Paolo more amenable.

3. For the inevitable numeric constants like pi ans such I used a class analogous
   to numeric_limits that cast long double literals.  IMHO I think the C++ standards
   committee (LWG) could do worse than to consider such a replacement to math.h M_PI, etc.

I like this idea. Was this considered for C++98? You could consider putting this into ext/constants or somesuch.
