I notice that ghci is loading integer-simple before loading base. This at
least explains why it cannot find a symbol from the base package - it hasn't
been loaded yet. So the question is why does integer-simple use any function
from the base package at all? I'm fairly sure that the dependency

Thanks Daniel.
I have just now built the 7.2.1 RC1 with integer-simple on CentOS 6 with the
same failure.
It doesn't surprise me -- there is clearly something in my setup that is
causing this problem.
But it's good to get it confirmed -- thanks!

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 think relying on the optimiser is OK, but don't forget that you don't
have the standard (+) etc.
oh okay, interesting. I think I'd best start by finding out where
integer-simple lies in the dependency tree.

is to
instrument integer-simple to report the sizes of integers it handles.
For example, if you use Rational, (even toRational/fromRational), you
might be handling Integers somewhat larger than you thought you were.
And this could also report on how often the integers get that large.

If you know that none of your code or libraries are using any
particularly large integers [how would you know, though?], then it
should perform alright. GMP, however
