Yes, good point. I've improved the error message. It now reports a
malformed class declaration.

hi,
i've found the reason with someone's help. it is because i used
%code instead of safecode in the gc file where i did callback.
thanks!

I tried the simple test:

You can do it specifically for GHC, not not in standard Haskell (except
grossly inefficiently).
To see how to do it in GHC, look at the implementation in the source
code (ghc/lib/std),
which is online (check the CVS repository link on GHC's home page).
Meanwhile you could use the IArray stuff.
Hi guys,
The library report defines
-- Diagonal of a square matrix
diag :: (Ix a) = Array (a,a) b - Array a b
diag x = ixmap (l,u) (\i-(i,i)) x
where ((l,l'),(u,u')) | l == l' u == u' = bounds x
but ghc, hugs and nhc98 all loop (trying to get and test the value of l
I believe).

Hiyas
A few more things I'm afraid :-(
The List module in the library report exports []((:), []) which, as I
mentioned in a previous thread WRT the GHC prelude, the report doesn't
allow in the exports list.
The block at the top listing the exports and types has been split into 2

However, I agree that sometimes you really want to be able to do this,
so perhaps we need another form of 'block' which doesn't allow *any*
