Hi all,
I have a few questions about the GHC lexer (currently using GHC Glasgow
Haskell Compiler, Version 6.13.20100320, for Haskell 98, stage 2 booted by
GHC version 6.12.1)
And I notice that when invoking the lexer I get a few unexpected results
that I was hoping someone could clarify.
Comparison of exceptional IEEE floating point numbers, like Nan, seems
to have some bugs in ghci (version 6.12.1).
These are correct, according to the IEEE floating point standards:
Prelude 0 (0/0)
False
Prelude 0 (0/0)
False
Prelude 0 == (0/0)
False
But these are

Could you say can I determine in Template Haskell that datatype X has

Hi,
I am asking if anyone has seen the following behaviour from GHC under
-threaded and heavy use of File I/O, network I/O and STM use. After
having run Combinatorrent for a while and then terminating it, we get
the following output from the RTS in GC statistics:

Hi,
I'm trying to download a file in UTF-8 with libcurl(1.3.5) and GHC 6.12:

main = curlGetString u [] = putStrLn . snd
Which doesn't print the characters correctly. If i read the file from local

Dear Haskellers,
I heard from a guy who was having problems with wxHaskell using GHC
6.10.x. I tried it myself and had the exact same problem occurring
using GHC 6.12.x as well. I am using the debian unstable version of
ghc6 package.

Just searched and found out that this is a ticket 4 months old
http://hackage.haskell.org/trac/ghc/ticket/3798 but it seems that it's
not only a GHCi problem. It doesn't compile with ghc either.

A worthy question indeed. The reason is that I am using registerDelay
This is really good stuff, Luke. I am interested in learning more,
