Oh, I agree that it would be really nice to have a way to write
high-performance code in pure Haskell --- it would be nice if I didn't have to
drop to Fortran anymore just because it makes it easier to write
high-performance numeric code! My only point was that it might not be
worthwhile to sp

Your question is actually deeper than some of the people answering you
seem to realize.
How does ghci decide what to do when you say
show []
?
The expression [] has type [a], which means it could be a list of any
type 'a', including Char.
Normally, when Haskell can't determine the type in this ki

This is our official 0.8 release. Anyone still using 0.6 should
upgrade.
Anyone using an earlier 0.8 release should upgrade too (and delete
~/.leksah-0.8/prefs.lkshp and ~/.leksah-0.8/prefscoll.lkshp).
There's lots of new stuff, so please have a look if you can. Let us know

That's life. ;) However, there is only a single point where you have

I just regret the fact that the SignalMonad can only be run inside IO. With

Use our threads package [1].

myDBusThingie :: IO ()
myDBusThingie = error "TODO"
main :: IO ()
main = do tid <- forkIO myDBusThingie

But like David said, this is only usefull if you plan on multiple

Hi,
I'm writing a program which listens to some D-Bus signals using

runs IO action in separate haskell thread when signal is received. My
program does nothing except signal handling, so after setting up
signals it has to wait ind

I wouldn't do this because the installed tools will be written with that
elevated rights, so you can only invoke them from an elevated prompt, which
is a bit cumbersome.

Right, the problem is that under windows 7 and vista the Program Files

without elevation.
You could go to the Haskell folder, and grand your current user full rights,
but any new tools installed will inherit the original
