This is one of GHC's classics. But it isn't a real error, only a

Hi!
After some months of silence, finally I made a snapshot of the weekend's CVS
version of GHC for Debian available.
As usual, it's compiled with "everything on", including a full set of
profiling libs in an additional package. If I recall correctly from a GHC HQ
mail, profiling is (at least

Hi!
I'm not quite sure, whether this is a bug at all, so maybe someone can
explain this behaviour to me:
Consider the following piece of code:
\begin{code}
import Exception
foo = do
res - tryAll (someObscureComputationThatThrowsErrors)
putStr "This is immediately printed: "
print res

Hello all,
I wanted to recompile some old programs with the
latest ghc from CVS. MutableArray wasn't known any
more. I do import GlaExts. What am I missing?

Hi,
I am having trouble with Show and tuples.
I have a data structure, say:

And a value, say:

Then try to:
