Re: GUI Toolkit
Hi, I already looked into into it. And for my current application its indeed ok. But I was also thinking of an application where the gui changes very dynamically, in particular triggered by network events. And in this case the only idea I could come up with was to generate the qml files dynamically and reload them quite often. Still this approach seemd very strange to me.

I use hsqml quite a bit myself so this is definitely a package I'd like to take a look at. Definitely keep us updated if you do move forward with packaging it in Debian but I certainly don't mind taking a crack at it, though I haven't quite grocked some of the issues you brought up. I recently talked to the HsQML author about debian package and he replied with the following: The only complication I can think of is that if the platform's GHC doesn't support Template Haskell then you need to use SetupNoTH.hs rather than Setup.hs. The latter has some TH-based compatibility shims for supporting older versions of Cabal.
