I think it would be great to have a benchmark, to test Integer
performance at various implementations. Perhaps it could test speed of
Int, Int64, Int32 as well (for computations that fit within them). I
suppose tight numeric loops are key to measuring performance in a useful
way (except for i

Thanks for the data point.
Looks like they swapp

I suspect (just guessing...) that a more reliable way to find out is to

Just as a data-point, my code rarely exceeds 128 bits (at least, beyond

I think opinions are divided on this.
Performance with word-sized Integer's is definitely important.
This is true.
We could start

GMP is LGPL, so if you use an official build or a private build from
unmodified sources, all you need to do is to ship the sources

that's true, (I wrote it), the current form uses a list-based
implementation with a lot o

GMP is under LGPL, which is designed
