Hi,
I noticed a difference in behavior between running:
ghci -package utils
And:
ghci
...
Prelude :set -package utils
On our system, the first one works (it finds all the right
dynamic libraries and stuff), but the second one doesn't (it
cannot find libreadline.so, and other

I don't think the native ld on alpha-dec-osf3 supports such a feature,
so we would (I assume) have to leave -split-objs in ghc even if we do
implement -ffunction-sections/-fdata-sections. (Would it just be a

Hi,
For a change, a teacher asking for help on behalf of a student
I have a student who wants to emulate S-expressions of Lisp in Haskell. He
came up with the following data type:
data LispList t = Atom t | LispList [LispList t] | Str [Char]
This works just fine. He then wanted to make it
This problem is probably caused by the unbound type variable in
values like (Str HEJ).
Try giving a specific type as the parameter to LispList:
(Str HEJ :: LispList Int)
The error message here could me more informative!

Interesting. The difficulty (which GHCi has too) is this. Consider
expr = Str foo
msg = show expr
Hugs wants to print msg. What are the types?
expr :: forall a. LispList a
msg :: forall a. Show a = String
Urk! What Show dictionary should Hugs use when
Simon Peyton-Jones [EMAIL PROTECTED] tries his hand at
inventing free theorems for qualified types, then concludes:
In which case we could report ambiguity a bit less often. How
useful this would be I don't know.
A lot. Any time one is testing the empty case of a bulk type. If

Hi all,
I though you might apreciate this:

He (the bastard) often uses his excuse board to confuse his helpless

You may say it doesn't matter, but in general that's not the case.
In the case of class Num, for example, we might have
expr = 3+4
msg =
