I am currently working on my master thesis which is designing and
implementing an usage analysis for Core. I have been working with
ghc-5.02 but want to start use ghc-5.04.2 instead. The problem is that
it seems like ghc-5.04.2 generates faulty Core code.
I need to generate Core for the entire

Obviously, yes.
Otherwise you would get evil non-local interactions
between different modules. And in practice it doesn't seem to be a problem
for ar/ld, because the base package and

Nice :) BTW, is readFile implemented with some strict evaluation
construct ?
I got another trouble: I need to build a record type like

Thanks for this pointer. Quoting from the
hello there,
To be honest I'm not very familiar with haskell and stuff
so don't laugh with my question...
here it goes..
We can represent a matrix as a list of lists...
which means that

Thanks for your answer, it's interesting.
