I see. That's very interesting.

I'm surprised to hear that. The last time I looked (a long time ago) I thought 
OCaml's support for such things (and unicode) was not that good but we do 
seem to be hearing about web-related successes with OCaml all the time and 
they must require working implementations of these kinds of libraries. Gerd 
always seems to be involved. ;-)

Yes. I noticed those Qt bindings for GHC being advertised recently but it 
turns out they are pre-alpha release have no applications using them and no 
Debian or Ubuntu packages providing them.

Haskell certainly has far more bindings to libraries than OCaml but it also 
has far fewer working applications using those bindings, which makes me 
suspicious. ;-)
