Stepping in bravely (where angels fear to tread? ;-) )
But not rushing in, I hope...
At a very quick slightly-informed glance, this looks a very useful addition to the Boost numeric repertoire,
Sounds like encouragement to me - I shall persevere.
espcially as it makes modern use of C++, including lambda - FORTRAN users won't like it ;-)
Having been forced to read FORTRAN, I have some empathy with them :-) One of the questions I pondered was whether I should use Boost.Parameter or not. In the end I opted to use it, and I think it works well. Using thirteen parameters does however slow the compiler quite significantly. There is also a slight clash with the Math toolkit library in the vault, in that it unconditionaly defines BOOST_PARAMETER_MAX_ARITY to a smaller value. BTW, just noticed that math toolkit is in SVN - will it be in the next boost release?
