Of course this definition is builtin and cann't be seen in the Haskell
source code.

As an author of HSQL and Visual Haskell I do agree that there is still
a lot to be done in order to make Haskell as popular as C++/Java in
the industry. We need strong support for GUI, Database, XML and many
other libraries that the other languages already have. The existing

Visual Haskell is now with BSD license and it is open sourced. See

Hi Brian,
The problem is that hs_free_fun_ptr is defined in a static library
(the Haskell RTS) while you have declared it with
__declspec(dllimport). In this case the compiler is tring tp optimize
the call and it is using __imp__hs_free_fun_ptr instead of
hs_free_fun_ptr. You have to remove the
I think that the C backend is heavily dependent on various GCC pragmas
but it should be relatively easy to do assembly backend that produces
MASM code.

Hello Haskellers,
There was a long discussion in October 2004, about the a FilePath
module which is currently used in Cabal. There was an idea to move it
to the standard libraries but since there were a lot of objections it
was removed.

Yes. I agree here. There should be two modules say:
System.FilePath.Posix System.FilePath.Windows. There should be a
third module System.FilePath that have to use the native path. It
should switch between the Posix and Windows implementations either at

Questions about Haskell for JVM or .NET was asked quite often and it
is really interesting question. Since the JVM and .NET machines have a

compilers is the
Hello Guys,
I saw that GHC already has complete support for Unicode character
classification. I tend to use it but I saw that currently GHC.Unicode
exports only few of all classification routines. Is it intentional?

The problem is that I have to use 'generalCategory' function which
isn't exported. It returns the general category which tells me a lot
more about the character.

Oh, Sorry! I didn't see it at first sight and I immediately went to
GHC.Unicode. In this case is the GHC.Unicode module still in use?
