Is this a bug in GHC? Can the warning be ignored safely?
Just ignore it... This warning from the interface file generator has

My reading of the report is that Hugs is right and GHC is wrong.
Do the Glasgow folks agree?
Yep - we're still trying to track down the cause though.
We've located the problem now - fixed in the next release.

Yes, adding cases for %edi and %esi should account for code that gcc

Victor M. Gulias submitted a little frustrating problem.
This worked:
any' p xs = [x | x - xs, p x] /= []
and the following generated a type error, unless type annotated
explicitly.

I've just played a bit with Hugs 1.3c which implements the type system that is
proposed for Standard Haskell. I came accross a limitation compared to Gofer
which I find quite unfortunate.
As an example for the advantages of multiple parameter classes Mark Jones gives:

Source-source transformations are there everywhere. Why everything
should be hidden inside the compiler?
Isn't this two separate things? Macro processors are useful for hiding
A discussion about referential transparency and I/O in Haskell popped
up in Comp.lang.scheme. The example was something like:
do
x - getLine
y - getLine
...with...

And so my question is what is the value of getLine? I had thought of
it as sort of a "placeholder" or
