Comment (by igloo):
I was hopeful that we could go with a really simple Haskell impl for
Integer, with serious Integer users using other types provided by packages
wrapping C libraries instead; this would avoid all the pain of sometimes
having to build GMP in-tree, it being LGPL, colliding with other uses of
GMP, etc.
However, the attached base.html (comparing nofib runs with GMP and
integer-simple) makes me think that that is infeasible, at least not
without a lot of integer-simple tuning. e.g.
{{{
Compile Times
-1 s.d. -7.6%
+1 s.d. +26.9%
Average +8.2%
}}}
