Simon, this could go in the 6.2 branch I believe

Hello,
I just installed ghc on Mandrake Linux 10, from the file

[EMAIL PROTECTED] is a mailing list; which distribution
did you use to install GHC?
I've been able to solve it with
cd /usr/local/lib/ghc-6.2/imports/System
ln -s io IO
cd /usr/local/lib/ghc-6.2/imports/

You mean these directories were present but lower case?
Yes.

I had a look. It turns out to be an utterly bogus and incorrect test
for overlap in 6.2.
As it happens, I've already re-written that part of the compiler in the
HEAD, to do lazy overlap resolution. In GHC 6.2 the instances

instance C Bool a

ghc-6.2.20040304 and later are release candidates for 6.2.1
Get them from here:

This is your last chance to test... I'm going to freeze the release on
Monday (15 March).

Hello,
Please have a look at the transcript below. GHC happily
compiles the file with the Makefile, while GHCi chokes on
it. I would be grateful for any insight into the problem.

I had to remove POpen from HXT to make it work correctly
with GHC 6.2. I think this because posix now includes
popen and so it conflicts with the version in HXT. Try
removing POpen.hs and doing it again, make sure you load
package posix.
Yep, it

Just a short note from my side: I've tested both the branch (not the
.tar.bz2) on x86 Linux and the .msi on Win2k. Both seem to work fine...

A few comments on the DData.Map proposal:
* nice work. I might start using it (instead of Data.FiniteMap)
just because the function names look better :-)
* argument ordering:
the existing Data.FiniteMap mostly has
f :: FiniteMap - ... - FiniteMap
while the proposal uses
f ::
I'm glad to see this progressing. However, it might be better to move
this thread to the libraries mailing list, which is specifically for
this purpose. Anyone out there on the Haskell list who wants to
contribute to discussion about Haskell libraries?
Hi Christian,

Hi,
I have a class:
class Sig a where
getName :: a - Id
getParents :: a - [TypeExp]
getMethods :: a - [MethodDef]
getFields :: a - [FieldDef]
and a few data structures that are instances of Sig.
They are ClassDef, ProtocolDef, SignatureDef, etc.
Now I have a type Def defined as:
The code is currently like this:
instance Sig Def where
getName (DefClass c) = getName c
getName(DefProtocol p) getName p
getName(DefSignature s) = getName s
getParents(DefClass c) = getParents c
getParents(DefProtocol p) = getParents p
blah blah blah...
But this seems very
Thanks! Oleg.
This works and it looks nice!
And now, my code can be like:
class FwdSig d where
(forall a. Sig a = a - w) - d - w
All the types that supports such forwarding are instances of FwdSig.
My Def type is:
instance FwdSig Def where
fwd f (ClassDef c) = f c
fwd f (ProtDef p)

Hello,
thank you for the references. Looks promising. I will read
it carefully.
A nice solution I really like was found by Alastair Reid. He
proposed to me (hope it is ok to cite this) the declaration:
data Salutation = [Either Char Name]
We think it will not scale well, too, however, it is
G'day everyone.
Some time ago a suggestion came up about passing types as arguments
to functions:
