It's not H98, so it has to be an option, enabled by a flag. Of course
you are free to put the flag at the top of every module.
Sergey's point is that the libraries are pre-compiled, so you can't add

More about instance overlaps with the GHC library:
I need to print in a special way the data of
[Equation], (Term, Term), [(Term, Term)], (Equation, Equation).
The first can be by defining showList in instance Show Equation.
But Show has not a method of showPair. So, I need to write the

You seem to be using special instances to do two things: add spacing and
remove extraneous parentheses. A neater way to do the latter would be
to use the precedence parameter of showsPrec for Term to control whether

I'd rather see HaXml updated to use Data.Map, perhaps with a
compatibility layer for older GHCs.
OK, I've looked more

Good question. We haven't made any tarballs of the testsuite, but just
grabbing the current sources from darcs is fine.
Cheers,

I noticed a five percent speed up by making local definitions global.
This is the first version with local definitions:
f = some expression based on mySet
where
mySet = foldl (flip Set.insert) Set.empty myList
myList = some constant list
Then I moved mySet and myList to

Maybe the global defintions are monomorphic, and the local defintions
are polymorphic. You could evaluate the types of the global types
That's odd. Making things more global can reduce optimisation
opportunities, but making things ore local should not. You can say
-ddump-simpl to get an idea of what the differences are.
If you can make a smallish repo case, I'll take a look, though perhaps
not before ICFP.

Hello all,
I've discovered that GHC doesn't deal very well with the following
program. It appears to diverge when running the following program
with 'runghc'. The main compiler can also be persuaded to diverge in
a similar fashion. Hugs exhibits correct behavior, ie, it prints
hello.
You and many others --- but the example is always the same!

Ah. My apologies for bringing up such a well-worn issue, then.

Nowadays -mfpmath=sse is better than -ffloat-store, because SSE2 has single

Thanks for the tip!
