Beware, to reproduce you need c2hs gtk+hs!
Luckily, I can use the -O switch (does that option mean turn errors OFF?)
to get a perfectly working binary!
ghc -c Get.lhs -o Get.o `c2hs-config --cflags` -fglasgow-exts -package lang
ghc-5.02.1: panic! (the `impossible' happened, GHC version
The native code generator only handles 'foreign import's with a
static target, which is why you're seeing this (HEAD handles
this situation a little bit more gracefully).
Use -fvia-C (or -O, which implicitly does the same thing).

Thanks for the bug report. I've checked in a fix for 1), but
for 2), I suggest instead of doing
void pj_set_finder( const char *(*)(const char *) );
you express this as
typedef [string]char* (*StringTrans) ([in,string]char* arg1);
void pj_set_finder([in]StringTrans arg);
as HDirect
I guess it's a [mis]feature, since 5.00 worked, but can hardly
imagine anybody could need it.

I searched on google, but had no luck.
My program is an implementation of

I might be dead wrong, in that case I apologize...
I just took the Windows installer and tried to put GHC etc. on my laptop.
I suspect that the installer absolutely wants to put the stuff in Program Files
and doesn't give the user the opportunity to install it on another disk.
Anyway, I have

Well, it's clearly a design choice. But in general laziness does not
come for
free. The choice made by the Haskell designers was that the 'array'
function
can consume and explore all its input before producing any result. It
just
give more scope to the implementor. Nothing too deep.

You don't say which version of GHC...
GHC 5.02.1 (which I advise you to use) installs in
c:/ghc/ghc-5.02.1
The installer doesn't give you a way to change this. (It should,
but we havn't found out how yet.) But once you have put it there
you can move it if you want.

I have a class whose instances can extract a field of type a.
Is there a way of referring to that type 'a' in the signatures
of functions that use the class? Sigh! That wasn't very clear.

I'm really frustrated that modules that you want to compile to
executables have to be named Main. I often have a module with a main
method that I use for testing or whatever (perhaps I want the gained
speed of an executable) but is, for the most part, a module I import
into others. I end up
hi,
the haskell report says that a program should contain
a module called Main, which should export a function called main
of type IO().
there is no requiremnt however that the function main is defined
in the module Main, it could for example be imported from somewhere.
so in your situation

Strange, I'm not annoyed by this at all though I supposed to
be. First I make module alone, and have 'module Main' and
'main' function there, then I use it in project, and change
the name to whichever I want and rename or delete the 'main'
function.
Anyway there can be a workaround (I didn't try
