Hi,
The Left Shrinking law for MonadFix in
fptools/libraries/base/Control/Monad/Fix.hs contains a typo.
Trivial patch is attached.
Greetings,

Good evening,
I just stumbled across a segfault caused when running the
following small program. (During an attempt to implement
single-assignment variables.)

Good afternoon,
the attached program is about 7 times slower when compiled
_with_ -O using ghc 6.4. Using ghc 6.2.1 with ddata's Map gives
the same behaviour.
Happy hacking,

Hi,
every once in a while, a screenshot says more than a thousand words.
And it's "global": ":i Bool" followed by ":i Int" shows exactly
the same symptom.
Groeten,

Hello again,
first of all, I'm not sure whether this is actually a bug-report
or a feature-request.
The three line summary is that in the following program, no
specialized version for ST s is created by at least 6.2.1,
6.4.20050304, and 6.4.20050308.

Hi,
while still trying to get Data.HashTable to work both in ST and
IO (I'll probably start complaining about optimizations not
performed once this is fixed ;), I bumped into the following
nastiness.
Comments interleaved with shell copy-paste-work.
% make clean
rm -f *.o *.hi a.out

Thanks, it's nice to hear that. Though I consider it a fair
deal: I
Hi,
6.4 appears to incorrectly infer some types in the attached code
when asking with :info in GHCi.
Both 6.2.1 and 6.4.20050215 "inferrings" (is there a nice english
word for that?) are added and commented out.

Hi,
while trying to modify Data.HashTable to support both IO and ST
without simply copying it, 6.4.20050215 again decided it doesn't
like me:
/tmp/test% touch *.hs

/tmp/test% /var/tmp/ghc/bin/ghc -O --make CompatHashTable.hs

Hello again,
while trying to get HashTable to work both in IO and in ST I
hit the following probable bug in 6.4.20050215.
6.2.1 does accept it, and the #ifdeffed-out version works in
both. When the typesignature is removed 6.4 does accept it.
Cheers,

Hi,
it's not going to cause World War III, but it does seem to be a
tiny regression since 6.2:
with an empty class, 6.4.20050215 gives:
*Main> :i EmptyClass
class EmptyClass a where-- Defined at foo.hs:1:6
^
where 6.2.1 gave:
*Main> :i EmptyClass

the subject almost already says it. In line 767 of mk/target.mk

Hi,
not directly a bug-report, but kind of a meta-bug-question:
Is anyone interested in bug-reports about PArr, or is it a case
of "completely broken, go fix it yourself"?
I do not need it, but was playing around with it and found that
both CVS and 6.2.1 panic even on something as simple as
